Making Concrete Dragon Eggs 

I like your sifting song. I used to have a huge cat named Spot. His theme song was "You weigh 16 tons, and what do you get? A bowl of kibble and a trip to the vet. St. Peter don't you call me, 'cause I can't go. I owe my soul to the cat food store."

is it just me that wants to see peter clean his blue mat with epoxy again. i found that video super satisfying !!!

Thank you for always posting the trial and error.

More videos with Mrs. Brown! She's adorable and you guys make a great team.

what would concrete powder do in resin? that's the real question. like, would the resin harden like normal or would the moisture activate the concrete powder? then would you be able to turn it?

Get you a man who can sing about sifting

that intro was great lol EDIT: your wife totally needs to be in more vids like this!

I searched this on buzzfeed, and I think the person who wrote the article made up the instructions to an already existing picture. The eggs in the picture look painted grey on their outsides, so I'm thinking they could've been made out of plaster. Someone should try this with plaster, which could possibly be stronger in this thickness than cement. Then use a bucket of warm water (so it sets faster) to rotate it in. Shouldn't take too long.

1:00 love that... it reminds me off how my grandpa sings when we drive around up north. love the channel peter

I like when you make videos with Mrs. Brown helping you in it too, you two feed off each others creativity and it's awesome!

More collaboration with Mrs. Brown, please! Really enjoyed this video :^)

"And I'm gonna imagine if there were dragons.." "'Which there are." 💚💚💚 I'm totally in love with you guys,.

Okay okay okay. I have an idea. It comes from the land of baking! Add about a cup of water to a balloon and blow it up to the size you want. Make the concrete a pourable consistency. DIP THE BALOON into the concrete and set it the way you want it to sit when hardened. Repeat several times to build up thickness. Seeing as you would be breaking part of the "shell" anyways, position the knot of the balloon where you would want to break the shell. This is the same idea used to create chocolate bowls or hollow chocolates. NOTICE ME!!!!!😢😢😢😢

10/10 thank you for keeping the song. I love when Peter and wife come together to do projects. Makes me happy ❤️💕

My husband spent about 15 minutes explaining that you needed pure cement not concrete mix because concrete mix also has sand in it that you probably didn't sift out. Pure cement is limestone and clay. No sand. 15 minutes..my poor husband

Peter my man! a facebook page called DIY & Crafts just uploaded one of your videos few hrs ago with half million views already and they not credited you! its the broken wood in blue resin ring. Contact them and get them to credit you, its going to go viral i think and you deserve the subs that will pour in!

Peter! Clean your mat again please? Watching the resin peel off is so satisfying!

I really enjoy you working with your better half. It looks like a lot of fun.

Backyard Scientist video AND Peter Brown videos in less then 5 minutes? yes!!!

i've been marathoning your videos to decrease my stress levels after my college midterm exams. your channel is so fun, it's super informative and you make every single project an adventure. thank you so much for sharing them all with us.

I love how the bowl mold has become a meme on the channel for its volume 😂

Cement/concrete is TOTALLY the wrong material for making hollow casts. What you want is ceramic, specifically slipcasting. Ceramic slip is really cheap (Less than 20 dollars a gallon), making a plaster mold is simple, and the only really tricky part would be firing the piece without a kiln -- but there's lots of articles online about how to fire pottery inside a simple charcoal kettle grill. Plus with a proper mold, you could quickly make multiple copies.

Peter Brown: "Saint Peter don't you tell me, cause I can't go," Me: "I OWE MY SOUL TO THE COMPANY STOOORE!"

OMG the bowl mold!! it became an actual bowl :D

I love that you show us all the failed attempts.

Your wife is so much fun to see in videos.

Awwww, y'all are such a cute couple.

backyard scientist and peter brown today is a good day

Plaster of Paris works well for this project, especially for inside the balloon. c:

Shoulda bought some cement instead of concrete

It may be a 5 yr old video, but some how I never saw it and as usual you and Mrs B are always so great together, and the vibe and energy is still as awesome today when you two are in videos together!

A paper mache version of this would be a lot simpler and would probably look similar

i love this channel so much, like how u show ur failures and how you go about fixing whats wrong and then showing the actual process and showing the final product, i love it

Great to see you and Mrs Brown working together! Great team

I'm sure that I'm not the only one, but I love seeing Mrs. Brown on your channel. she brings a whole different perspective

Instead of sifting all that, why not just buy a bag of straight cement ?

I really loved watching this video. Not just for your problem solving with the egg, but you and your wife are so enjoyable to watch.

Again as I said before, you have an amazing singing voice.

Perseverance paid off Peter, cool looking Dragons Egg, great video. Cheers Mike

I wish you uploaded daily! keep up the great work.

I love it when Mrs. Brown is in the videos. You guys rock!

Thank you so much for Lovely videos, inspirerad by your Dragon eggs i did some of my own today. But i did mine With alabaster plaster instead. They turned out lovely:)

Loved this video! More Ms. Brown! Fun to see you show a competent beginner making stuff - sort of represents for those of us who are just beginners, too...

Peter I built some of these a few years ago you have to use Portland cement. I tried what you did with concrete and had horrible results you have to use the Portland cement. even then it is very hard to get one to stay together.

Shop time... shop time... shop time.... I get so excited when I see shop time in my feed

Got johnny cash vibes from your singing haha! Loved this video man. Love to watch and listen to your creative journey through projects.

You two are lovely to watch together. It's so nice to hear you both get on so well and enjoy each other's company.

she is too cute! i love videos with your wife! we need more of both of you!

I love when he starts singing in his videos. it makes me so Happy

The constant turning is the same way Easter eggs are made. Pour into a mould and machines turn them in every direction. I feel you might have more success if you keep it constantly in motion until the concrete is fully set.

Lovely having Mrs Brown in the video! Those eggs look cooooool.

"we're gonna need a lot bigger than this" *brings black hole mold* "that's plenty of room right?"

I saw the video on Facebook and really wanted to try it! Glad you guys beat me to it before I went out and spent a bunch of money on the supplies.

Now you have to make a tiny dragon to go inside the egg

So so happy you showed this. Yours turned out just amazing.

I think the poured look on the outside is much better than the smooth ones but if you want smooth ones filling the balloons with plaster of paris rather than concrete should work.

you and your better half seem genuinely happy together! happy for you both thats hard to find

Great video! Maybe you could find a baby dragon candle to put in it? Or make a baby dragon, I dunno

You two are so cute together! Love that you show the Gauls, then the even better method!

concrete is not just some form of "sand". To crystallize the concrete quick additives are also in that "sand". To dry very liquid concrete it needs more additive. So the concrete you used is not suitable for this project. Overhere in the Netherlands we have special concrete, in boxes of 1 kilogram, for these special projects. When mixed it has the consistency of eggwhite and hardens within 15 minutes. There...now you know.

Hi Peter, love your videos. What you mate from that concrete mix was mortar mix => concrete = (cement, sand, aggregate + water) when mortar = (cement, sand + water); 2nd u could make a negative mold of an egg (styro), hang an inflated ballon on the inside, and fill it up with mortar, thin fi=3mm iron wires => great for reinforcement of the mortar. Also possible to make the crack line out of thin styro strips glued to the balloon

I loved this video!!! Buy pure cement next time!! :-)

Peter Brown & Mrs. Brown ... outstanding video, really enjoyed the whole process. Very entertaining

1) More collabs with the wifey! 2) I had no idea you were on Patreon, how did I not know this? Subbed. 3) Nice recovery, they look great :)

Peter, I have a suggestion. Toilet bowls, sinks and many other china or porcelain things are made like this: 1) Make a mould out of Plaster of Paris of the desired finished article; might be two or three or more parts that all fit together .precisely', and leave a 'filling' hole (see note at bottom) 2) Make mould slightly bigger than desired to allow for later contraction. 3) Mix up some fairly runny (about double cream consistency) Plaster of Paris (or similar), close the mould parts together having used some kind of 'release' agent inside the mould and fill mould. 4) allow mould to sit still for perhaps 30 - 60mins (Trial and error) 5) unplug/uncover filling hole and empty STILL LIQUID contents into a container ready for next use. Hopefully, the Plaster of Paris mould will have absorbed quite a lot of the moisture from the liquid PofP immediately next to the mould. Perhaps to a thickness (trial and error) of 2 - 4 mm 6) Gently heat mould to evaporate any remaining moisture until PofP is completely set. 7) separate mould parts to reveal a glorious dragon's egg. The filling hole might easily be the hole in the egg that you look into when it's finished. 8) thoroughly heat the mould parts (but not necessarily to a high temp) for next use. The PofP needs to be as dry as possible in order to absorb moisture from the liquid PofP Hope that helps, but if you need any further explanation, let me know. Regards Mark in the UK. p.s. Love your channel

If someone wants to replicate this over-mold style make sure that each pour is done somewhat close together because concrete will crack and fracture on the join lines if one is wet and the other dry. What they probably did in the buzzfeed video (I haven't seen it) is use a retarder admix (chemical addition) to slow the set time and make a mixture that is very close to a .5 water to cement ratio (W/C ratio); Higher than that it may not set at all. The mix they gave (1/3 cup water to 2/3 cup cement) has roughly a W/C of .17lb water /.55lb cement (.31 ratio). Overall I have no idea how they would make a hollow concrete ball inside a single balloon with a thick or a thin mix. Loved the video Peter, keep up the good work!

U have no idea how long I've been watching this guy this is the first time seeing miss brown 😱😱😱😱😱😱😱

May try their methods but with thinset instead of concrete, no aggregate and it has latex as a bonding agent.

aww so awesome to see Mrs. Brown in the videos too! ❤

I would have put the tied ballon in water bucket it would be round

Very nice paint choice, looks so cool!

0:57 ayy Tennessee Ernie Ford, mah' man

The copper interior looks great with outside concrete! Great job guys!

I love your wife's Zelda top! 😍

Thanks for letting Mrs. Brown for this video!

I know you used concrete mix, but would mortar mix behave differently? Or Rockite? I just wonder if the drying times are skewed because the concrete mix is formulated to dry with the rocks in it.

It is pretty amazing to go to another person's channel and see Peter Brown on just about every other comment. I tried this using mortar mix instead, blowing the balloon up first to stretch it out some. It worked on the third try, I had to get the mix just right (first time too thick, second time too thin)..

99.5% certain they used plaster of Paris in the original video

I really love the way it turned out! Good job! Mrs.Brown should be in more videos!

well theres your problem its foolish to even think watching buzzfeed is a good idea

It's great to see you and your wife working together. Fun video

"That's plenty of room, right?" Sure, it's a 75 oz mold! I mean 85! I mean black hole!

long ago I made concrete eggs...I used the larger plastic easter eggs you put candies in. I remember a friend had me spray oil in the egg forms first and after pouring and letting set just a bit, we carefully put them together. they hold the shape, and you can roll them to make sure it stays all coated. they turned out well, I didnt use tons of water..its like making pancake batter for me, you know when its right. it you put them together before they get all really set up, they stick together without a seam to speak of. its been a very long time. I am going to give it a try again, now you reminded me..but balloons aren't something I ever thought of using. plaster works really well too!

"I saw it on pintrest." -drops mask and walks out of the shop forever-

I like when you and mrs brown work together on things its very sweet to see :)

You guys are such a cute couple ❤

GREAT attempt Peter & Mrs Brown. If we were watching Mythbusters this would definitely be BUSTED!!! Yes not all internet videos can be relied on.

I like this wife/husband video but I don't think she will last long she already lost half a heart just from this project. haha great video

I love when Mrs. Brown is in the vids! She’s so pure 😆

Why not try resin inside the balloon?

Couple goals!! Good team work, regardless of the result.

Couldn't you fill a balloon with the concrete slurry and then put a second balloon inside it and blow up the second balloon?

This is very kewl! I have wanted to make dragon eggs for a friend of mine for a really long time. I can't wait to try this!

I would have used a tabletop concrete mix instead of killing my lungs with sieving.

What I found good was by blowing up the balloon first then put it over the end of a bottle which contains the cement powder. You can fit alot more cement inside this way. Then do the same thing with water and shake it around

I'm gonna steal the magma egg thing for my dnd campaign

I have a few suggestions for this project: - Do not sift the mixture as fine. Sand give it more structural integrity. - Fill a balloon with the power/sand mixture - Add another balloon inside the previous balloon. - Then add the water, and mix it well. - After the mix blow up the inside balloon. this will hopefully create an even spread across the whole surface. - Once cured, and you want to open it, use a sharp object to cut it open, do not smash. Concrete is much weaker against focused pressure like cutting. This way there is much less chance of breaking off more than you wanted.

painting looks like a solar flare from the surface of the sun ;o

They look so good together. Both egg & paint, and this dude with his wife.
