Instructions

Difficulty: Easy

Things You’ll Need:

  • dry ice
  • water
  • plastic bottle (plastic only)
  • friend with cellphone
  • gloves

Step1
Make a hole in the cap. Make sure it's not too big or it will reduce thrust and power. It should not be too small either, or there will be an explosion.
Step2
Find a way to seal the hole with something removeable. For example, tape is good.
Step3
Use any method to provide pressure without torsion (twisting), such as dry ice with water, or pump air in from a bike pump.
Step4
Put the cap on with the pressure item in the bottle. Make sure the hole in the cap has tape or something removeable.
Step5
# Let the pressure build up inside the bottle, not too long or there will be an explosion and not too short or there will be no thrust.
Step6
8. When the pressure is ideal, remove the tape quickly. The pressure should blast out the hole for acceleration. The rocket's pressure will accelerate it and it will go 10-25 meters.
