David and Johanna fills a huge water balloon and then slice it with the Rocket Knife. The sun was setting and the lighting was golden which produced beautiful slow motion.

Rubber Band Ball. It must happen.

@didactylos4diddy474 7 лет назад

Very pretty. I especially liked the compression/expansion waves as the knife passed through

@NicoMyers 7 лет назад

Beautiful! You could pause the slowmo on one frame for a while to enjoy it without YT compression doing its thing

@LowLightVideos 7 лет назад

0:28 - If only your Water Pump were Rocket powered you'd have water pressure. An Oobleck Balloon would have been better because it would have _froze_ for a moment.

@kaikart123 7 лет назад

He already done oobleck baloon

@GameTrailerGuru 7 лет назад

Do you think if you mount the knife on a angle it would give it more of a slicing action?

@raincaller4927 7 лет назад

I had my doubts but that was pretty cool

@BLThackrey 7 лет назад

add colour to liquids ! Rocketknife 3 bags of coloured flour ( the 3 prime colours ) and put a sheet of pre-glued paper/canvas around it .

@bigbuckoramma 7 лет назад

Joerf Sparv is already getting excited for next week's Rocket Knife.

@PressTube 7 лет назад

You have probably said this somewhere in one on your videos, but what slowmo camera are you using? And where are you located?

@chanjyj 7 лет назад

PressTube Sweden

@djbro808 7 лет назад

PressTube looks like it might be the chronos camera but I'm not sure

@tornadoswe 7 лет назад

yeah, thats the chronos

Noticed for the first time: by the time the water droplets coalesce, they are mostly of pretty uniform size. I'll bet there are physics guys who can tell us why.

@kevinagnew1519 6 лет назад

Followed you since your time with Flight Test, same with Slow-mo-guys not sure how comfortable I am with the two world mixing. If I see Bixler and Dan on the same video it could be scarring.

@Bicketybam68 7 лет назад

And now for a really trippy experience, watch it from 1:45 at half speed on youtube and you get to see David's reaction to watching the slowmo... in slowmo! Drunk David! :D

Rocket Knife vs Fire Extinguisher

@diethylcd 7 лет назад

Hmm,I think you should try rocket vs police shield it`s strong enough,so it will be very unpredictable experiment.Hope you have readed and liked this comment

@torquedude 7 лет назад

Awesome slow motion footage👍

@NikoMoraKamu 7 лет назад

some ideas: a skull in ballistic gel inside a helmet , a pork/moose/big animal head , a tire , a microwave , a laptop , a big magnet and some a little more destructive , rocket knife vs axe , rocket knife vs rocket knife(METAROCKET KNIFE!) with different steels this can be pretty interesting test, rocket hammer vs anvil i can made new knifes for you on 1095 or O1 steel if you want ^^

@GiulioBerti 7 лет назад

Rocket HAMMER!!!!

@nerys71 7 лет назад

Ok. you really need to do this one again. and you need to do some building first. you need to build a gantry OVER the target zone. and then do another balloon filled with water but this time shoot it from DIRECTLY over head with the slow mo camera. I am curious if it actually "splits" the water or not.

@joematthews3379 7 лет назад

BITRATE!!!!!!

@Kael87full 7 лет назад

you need a faster camera bro hope you get some sort of support for that ! keep the nice work man happy to see you in a regular phasion again ! cheer me up every time thx

@brocktechnology 7 лет назад

I wonder if it's possible to fully fill the balloon on the ground and mount the blade underneath the sled?

@randomhouse56 7 лет назад

Can the Rocket Knife split a log?

@JuggaloJD420 7 лет назад

i love how rocket knife can kill everything. except that pile of hay. (next video try a log., Or hay.)

@plasticbutcher 7 лет назад

@rosedruid 7 лет назад

Rocket knife vs table top. Try a counter top piece or even just play wood without the gap.

@Rhythmattica 7 лет назад

when that balloon goes, i keep thinking of Dredd 3d. Slo Mo. yeh!

@tensuu 7 лет назад

Ni borde titta på slowmotion klippen tillsammans istället. Det känns alltid så konstigt att du ser det först och sen kameraoperatören.

Can rocket knife cut your table in half?

@joshuamiddleton5274 7 лет назад

You should make the motor bigger and the track longer.

@dwcobb43 7 лет назад

As Josh Bixler said to you during rocket plane video "can you say HUGE again" lol

@ben45248 7 лет назад

You should upscale the 1080p to 4k so we can watch with better bitrates.

@HomeGrownPyrotechnics 7 лет назад

why do you use sorbitol? there are much cheaper and IMO easier to work with sugars out there

7 лет назад

+Home Grown Pyrotechnics such as?

@HomeGrownPyrotechnics 7 лет назад

sucrose, dextrose, xylitol(very similar to sorbitol as far as i know). as far as i know sorbitol is only used because you can pour it but i would much prefer using sucrose(table sugar) because you dont have to prime it and it has much less wastage, at least in the way i prepare it by dissolving the ingredients in water then boiling the water out completely then it will have the consistency roughly of playdoh which is mush less sticky so it can all be collected out of the pan and then pressed into the mould. just beware that it burns quite a bit faster and produces more pressure so you would have to increase the nozzle size.(one helpful thing is that ethylene glycol(antifreeze) helps make the fuel softer) btw i would highly recommend that you come join the SUGPRO mailing list through the freelists website, all the boffins like Richard Nakka, jimmy yawn and even the guy that built the rockets for the mythbusters rocket car is there! please come, the people are super helpful and you can get way more specific info from the guys who specialise in this than any website can provide. btw it was through the sugpro mailing list that i heard about what you were doing with rocket motors :)

@ShenRC 7 лет назад

@Designandrew 7 лет назад

you should try pointing the knife forward (horizontal)

Reinforce the table fill larger balloon with water and use the katana 😁

@brocktechnology 7 лет назад

Okay hold on, I couldn't have heard this right. Did she look at the wet red rubber sheet and say "I want to wear it to bed"??? 1:47

@heukelummer 7 лет назад

can you try to cut a bottle with mapp gaz? would be nice to see liquid gas splashing and being ignited by the rocket

@patfilice 5 лет назад

Is that the music from dredd slow mo scene

@BrennanCallan 7 лет назад

It might be good to see if you can add other types of videocameras to your collection that would observe on the infrared spectrum, or other ultraviolet spectrum and it would have shown even more unanticipated reactions for the final product. I do appreciate that those cameras could be more expensive than what you have now. bye Brennan Cinematographer

@johndavi1230 7 лет назад

Add dye to water for more colors!!!

@AlexJoneses 7 лет назад

THATS EXACTLY SHAT I THOUGHT, I HAD THE SAME PROBLEMS WHEN UPLOADING WITH EVEN A 16 MB/S RATE!! JUST THE WAY IT COMPRESSES. maybe you should set you max bit rate to something lowered?

@CKOD 7 лет назад

Upscale to 4k, upload in 4k, watch it in 4k even on a 1080P screen, for dank bit-rates

@karlharford155 7 лет назад

If you do the balloon again put some drops(bottles) of food coloring inside first.
