Launching Rocket-Balloons Down 39th Street – Kite and Rocket Research

Launching Rocket-Balloons Down 39th Street

Rocket-balloons are great. They look a little bit like balloon-animal balloons, except they have a slightly longer neck at the bottom and a small rubber weight at the top. This causes them to fly in an upward direction as they deflate instead of just flailing around wildly like a normal balloon.
