2 Liter Rocket

Looking for something exciting to do? Try building a water powered rocket out of a 2 liter soda bottle. This can be completed in less than half an hour with simple household materials.

Materials:
   1 Two liter bottle
   Cardboard
   Card stock although construction paper will work
   1 Cork
   1 Schrader needle
   Tape

Tools
   Excato Knife
   Scissors
   Bike pump

Step 1 The Cone

To form the cone simply fold over the corner of a sheet of card stock or construction paper and continue rolling until you get a cone with a base that is the diameter of the bottom of the soda bottle.

Tape the base of the cone to the rocket using as little tape as possible and a strip of tape running up from the base of the cone to the tip where the paper ends.

i saw a contest on Japanese TV which was a bottle rocket contest based entirely on distance achieved.

the winner was a multistage rocket as made here. it had launching tracks and went about 500 feet.

awesome.

For a school science class we made these. I never got to see mine go up though. It went the highest from what I was told, but I wasn't in school that day because unfortunately the night before was my grandfather's memorial service and my mom turned off my brother's and my alarm clock. She didn't want to make us go to school the following day, she thought it would be too hard. Anyway, my science teacher was also the photography teacher, and even though she set my rocket aside so I could see it fly, her photography students threw it out. I've been meaning to make another, but didn't have any way to get it in the air.
