If your going to recycle your water bottles anyway, why not have a little fun with them first. With this easy and fun thing to do, you can reuse your water bottles.

If you leave a little water in the bottom, there will be something that looks like smoke coming out of the bottle after you shoot.

Step 1: Materials

What you need: 
A water bottle

Step 2: Twist the Bottle

What you need to do now is put the cap on the bottle, then just twist the bottle.

Step 3: Shoot It!

You now want to hold the bottle twisted, and then you want to spin the cap off really quick. The pressure in the bottle made from twisting it will propel the cap off once you spin it with your thumb.

Step 4: Look at the Bottle!

I guess all the pressure combined with the water makes some sort of gas, and you can see it coming out after you shoot. It should look like this.

Step 5: Reloading

You should have something that looks like the picture below, all you have to do is blow the bottle back up as much as you can, find the cap, and repeat the process. Each bottle can get about 2-3 shots, depending on how well you can blow up the bottle.

Step 6: Have Some Fun With It!

Don't Shoot at People, its surprisingly powerful. Remember to Recycle it when your done!
The "gas" is just water that condensed when pressure in the bottle was released.
I LOVE doing this with bottles!
Haha I KNOW!
