Backpack Jets ?

[NascarFool]

I saw this vid on another forum. I did a search and found nothing, hopefully it's not a repost. VID

damn.

:laugh:

even if it is a repost...

Japanese guy with water rockets?

 

[Mrvile]

Mail me one!

 

[LeetViet]

Aren't they called jetpacks?

thats total bs...theres no way that would lift him off the ground , much less propel him across a lake like that (at least im thinking this is the same one thats been circulating the net for a while now)

Compressed gasses/water have strange tendencies.

I love the Rockman (Megaman in the US) hat he is wearing.
I have a hard time believing that compressed air that can shoot him that far, wouldn't blow up the bottles before they reached high enough air pressure.

That dude fell out of the top of the ugly tree and hit every branch on the way down.

 

[cjchaps]

It looks like he is going too slow for it to be real??? that's just strange...

yup repost

I believe it.... its not shooting air that propels him, its the shooting water that does it.... havnt you ever seen those little rocket toys where you compress the air into a bottle that has water? It gets some amazing takeoff thrust

 

[91TTZ]

It's fake. You can easily tell because the center of gravity is way off. Also, even when the water rocket is shooting water out the side, he keeps going in a straight trajectory.

In reality if those water tanks were on his back like that, his weight in the front would make him flip over frontwards. Also, a water rocket that had enough power to lift him off his feet straight up would accelerate pretty fast when going sideways, not make him slowly float across the water like that. This one's easy to spot.

i dont think that breaking the laws of physics is one of those tendencies, moreover water is non-compressible, itll bend piston rods if it gets in an engine.
yes weve all seen those physics experiments where you pump up a 2 liter full of water and air with a bicycle pump and it shoots off, but that does not have enough power to lift much more weight than the assembly itself.
even if you tried more 100 of these , i doubt you could get off the ground
