SHOOT FOR THE MOON...OR MAYBE YOUR ROOF!
Tuesday, July 14
The pencils are taped to the 2L bottle as the stand. Fins and a nosecone could also be created and attached with cardboard or another household material (not necessary for flight). Vinegar and baking soda are added to the bottle and the cork tightly seals the neck. The bottle is flipped upside down to stand on the pencils while pressure builds. When the cork pops out, the vinegar forces itself out of the bottle downward while the rocket is propelled upward. My kids and I made these at home and actually work quite well. This should be fun and easy to make at home!
