I think for the bottle tap, simply lowering the spigot to be level with the bottom of the bottle would have made it much better so you wouldn’t have to squeeze or jiggle the bottle to get the last bit of soda out. That I think would also help with having to use a push pin to create air holes, because you wouldn’t have to worry about removing the bottle to pour out the rest of the soda since the spigot is low enough to avoid the physics issue
but then it would require being on the edge of a table etc, like a boxed wine and then you couldn't set your cup down. but unlike a boxed wine, in a flexible bag that doesnt need air, the coke bottle is rigid so you need air to get in or you're facing a vaccum issue, so youll still need a vent to maxiomize flow. like the old gascans with the vent cap, before the new obama gas cans came out that take 5 mins to drain. i wonder how boxed coke w/ a plastic bag would work... the co2 would probably fill up the bag and the coke would go flat quick
@@blehh_mae Not true. Plastic water jugs with spigots at the bottom work very well. The people who invented this soda dispenser had no clue what they were doing.
A redesign for the first one would be easy, you make the spigot level below where the lowest point of the bottle, than put it on secure stand. That way it is still higher, well still works. Also, I would recommend a special item to not only put a hole in the bottle, but act as a seal when you are done.
this guy is cool, his videos are so simplistic that it shows us gadgets for food/beverages and shows if some gadgets shown online actually work properly.
The silicone can holder was really nice, it'd be fun to have at an outdoors party (cue someone drunkenly tipping everything over and now all the drinks explode when you open them-- great fun)
The first gimmick could easily be corrected by removing the stem completely and allow the spigot to be below the exit of the bottle. How did it ever get past testing by trying to sidestep Pascal's Law?
Would need a good base to make it stable, being top heavy and all (maybe a clamp?). Add a one way vent tube suitable for 2L bottles and it won't deplete the bubbles as fast AND not require putting holes in your bottle. Alternative Idea: a pour spigot with one way air tube to let the air into the bottle and stop the glug-glug effect. Less material/complexity.
Did anyone notice the funny badly-written warning label in the fridge @ 3:43? That thing must have been made in China or Japan and Google-translated to English. 'Do not fill the carbonated beverage such as cola, cider (soda pop) and contained particle beverage/sugar and particles which is contained in these beverage may be reason of fault).' Lol
1:14 That's because there's no air pushing the liquid from above. You need to poke a small hole on top of the bottle, then the liquid will be pushed out whenever you pull the lever.
I actually would use the bottle can-topper to drink Arizona tea cans. Cans, while cool, are kind of a pain to drink from sometimes, and if I'm drinking from a can, I want it to be soda. But you get more tea in a can than in a bottle, and I haven't seen every flavor in bottle-form, either. Hence the bottle-maker. Plop it on, and right away you've got a big bottle of the stuff. Pretty cool (huh), I must say.
Thank you Dave Hax! I’ve been looking for a solution to pouring squash for my dyspraxic 7yo. He can’t lift and pour the bottles without making a mess! I was thinking about using optics, but worried about his hand strength. These bottle pumps are ideal and I bought two as soon as I saw your video. Thank you 🙏🏻
I've had those can toppers to keep bugs out and they worked great to take cans on the go or at least attempt to stop going flat though it still did anyways after so long.
I think I know at least part of how we can fix the design of the first drink dispenser to make it work. You give it a base that raises the bottle above where the drink comes out, so that way Pascal's law that causes the second problem mentioned in the video. Maybe the faucet of the gadget can be altered to let air flow in from outside to fix the other issue outlined for the first gadget?
I mean some of the gadgets seems cool, like the can stacking one. And yeah like I gaster said if you don't want it, don't buy it. If the argument is "well they are still produced and therefore waste our resources" well... Not really? Because nothing really is a waste nowday, most things get recycled one way or the other
@@UncleRussian. free physics lesson that will last you a lifetime: if you put your can standing on its bottom (as designed), it doesn’t roll over. Moreover, you can stack them and evennread the labels to see what’s in them. Pretty cool, huh?
@@rodintoulouse3054 free spacial awareness lesson that will last you a lifetime: if you stack them up like you described 1) you can only stack so many until they'll be too high to reach for normal people. 2) if you apply too much force via say a human elbow then your whole stack will fall over. With this gadget shown in the video the rubber prevents them form moving and the chance to knock them over is way less. Pretty cool, huh?
The bottle adapter for the soda can works great for travel since if you knock it over it doesn't spill everywhere. The issue is that it snaps on too snugly, and can be a real pain trying to get it off the can when the can is empty so it can be washed and used again.
I thought it was cool when I bought one but I put it on a can and the carbonation built up so much that it flew of and hit the ceiling shattering and sending sharp pieces of plastic flying everywhere.
for the screw on tap, I suggest the maker of this gadget make a pump with a checkvalve that we can manually regulate the pressure within the bottle. the checkvalve prevents backflow into the pump, potentially spilling everything
for the first one the solution is simple, all they need to do is raise the area that the soda bottle screws into, and have the spigot be leveled with it or be below it, that way the pressure is sure to force it out that way. there could also be an included air valve that allows air to follow behind the soda but doesn't let the soda come out, kinda like how the olive dressing bottles work where they have that second little tube that functions for air flow.
It's been quite awhile since I last watched this channel! I loved seeing the quality of the content always high! *The pretty cool huh never gets old that's for sure!*
Dave if you dont mind me asking, how long does it take you from having a video idea to posting it? This means ordering the items, waiting for them to arrive, recording, editting and posting?
I’d figure at least an entire month for the whole process, although I don’t imagine that being a particular filled month of work. I also think that he is likely doing these videos back to back, and so he’s able to do more work within a month’s time frame
The tap itself needs to be ‘rotated’ around so it points down; that way the drink doesn’t find its own level. It’s a great idea, it just needs some extra tweaking
The bottle tops, I remembered my mother buying some, they are a pretty cool concept to keep your drinks from spilling. Though it can still pop off if you’re not careful
The spigot needs to come with a piercing mini pump you insert into the bottom to pump up the pressure inside the bottle. Then it would work without having to squeeze it, or having to make the drink go flat. It could also be redesigned to have said small pump device attached to itself so you could pump more air inside.
The vottle pour device should be built up on more plastic with the spout below the attachment point. That way the liquid never levels out and pokong the holes becomes useful.
I acually have a dispenser like the 1st thing, only it has a tube you would slip into the bottle, along with a pressure cap, I think. No issues on air flow!
Me: can i have some cola? Dave: Yes wait a min Dave: *spends 27 mins trying to put in the dispenser* *after he finishes putting the dispenser in* Dave: pretty cool huh? Me: 🙃
The first gadget has a different version with the spigot on the bottom which partially solves the problem. What I don't get is why nobody is combining the dispenser with the pump that pressurized the container. It would fix the air pressure problem without having to poke holes and increase the longevity of the soda.
The problems with the soda bottle tap would be cured by lowering the spout and having it hanging over the edge of a surface, and extending a tube up into the bottom of the bottle to allow air inflow. An electric pump could also improve the performance, although pumping soda is likely to agitate it too much.
