This is one of my funnest inventions so far! With this robot, you can drive around, and squirt people with water. I used 2 pneumatics tanks, but instead of filling both of them with air, I only filled 1 with air. The other, I filled with water. I have everything set up so when the switch is flipped, the compressed air in one tank shoots into the other tank and pushes the water out the hose. The stream of water has suprisingly good range up to 12 feet!!, and gets the person pretty wet, especially when you aim right! I have a lot of fun driving this thing around. The only bad thing is that I have to refill the tanks after every shot. if I had 1 more tank, It could have 2 shots. I think that the coolest thing on this is the squirting part, but the base helps a lot too. It has enought power so I can stear it into a place with lots of bumps and obsticles without getting stuck. I have to use the Lego remote control so I can get a perfect shot, so there isn't a program.
