He'll learn! But he made a cool looking rig!

When I was was home from college long, long ago the little neighbor boy came over with a little plastic rocket you filled up with water that sat on a small air pump. You pumped up the little rocket and pulled on a latch to release it and with the pressurized water as a propellant, it would fly 30-40 feet into the air. Jokingly I said to our little neighbor fill it up with Coca-Cola, pump it up, shake it really well, then release it. Later he came to me crying and said he did what I said, and it flew so far away he never found it!! I felt so bad I went out and bought him a new one!! Now following!
