I've made water grenade out of a water bottle and schrader valve. I put fitted the schrader to the cap of bottle, filled the bottle with water. Then used my air compressor and brought the PSI to about 70. When I throw it, it hits the ground and explodes, but I was wondering how safe this is, If it explodes next to someone or in your hand.

This idea is definitely not safe. Schratnel does not appeal to most people in a simple water fight. If the bottle explodes near someone, that person would get wet but also cut and hurt. In all, a water grenade like this one is not a good idea.

another thing is, the speed at which the cap flies off with the schrader in it could seriously hurt someone. yeah , this idea is definitely not safe

The idea stated above is interesting and definitely innovative, however unsafe unless there is a good way to control shrapnel. If you can find a way to drastically reduce or preferably eliminate the amount of flying plastic, it could be something interesting, as a simple schraeder valve is something easier than other designs.

I heard, most likely on iSoaker, that wrapping a bottle with densely-wired chickenwire could prevent plastic from flying, however that leaves the cap to worry about. If you could cement the cap on, perhaps it would stay on, leaving the only thing flying through the air to be water.

Just my thoughts.

If you want a grenade, just use a water balloon. You can toss it and it will explode on impact. Plus, the enemy can't fill it and use it against you.

Just an idea that occured to me...what about something like a sponge ball encased in a squash ball covering, with holes drilled into the sides? The idea would be that the ball would compress on impact, sending water out of the holes.

they already sell water bombs. Foam balls that hold a ton of water and soak someone when they hit.

I'm sorry to sound overly negative, but in this case, I'll make an exception.

WHAT WERE YOU THINKING???

Ok, just had to yell that.
This is a very dangerous system and even if it were somehow safe, I really don't see the point of making something like that. You would have to build every single grenade by hand, make sure they are completely air tight and use an air-compressor to power them.

True, but the idea behind my design is to disperse water even when the grenade merely hits the ground.

Ok let me talk about a bad mishap with a coke bottle bomb. When I went to throw it, I guess I was too rough with it and it exploded in my hand. Luckily I was holding it with one hand by the rim (which is the strongest part of the bottle). None the less the plastic cut my arm pretty good. The plastic is very sharp. Sure, I got soaked by it and it was funny afterwards, but not a safe thing to do.
