Make Your Own Bottle Rocket

Add some pressure for an impressive blast-off!

DIY Rocket Craft

The journey is the fun part, as your kid will discover while making — then launching — a homemade bottle rocket! Some household materials and a grown-up’s help are needed for this one.

What You’ll Need:

  • Empty 1 liter plastic bottle
  • paper
  • duct tape
  • modeling clay
  • ruler
  • thin cardboard
  • X-acto Knife
  • bottle cork
  • nail
  • bicycle pump

How To Make:

Step 1: Roll paper into a cone and wrap with duct tape completely to reinforce it.

Step 2: Tape the cone to the bottom of a bottle.

Step 3: Wrap a piece of modeling clay around the top of the bottle, and secure with duct tape.

Step 4: Using a ruler and X-acto knife for straight lines, cut four even triangles out of thin cardboard.

Step 5: Tape the cardboard triangles to the sides of the bottle, so that they are just below the bottleneck.

Step 7: Use a nail to make a small hole through a cork.

Step 8: Fill bottle halfway with water and inset the cork into the bottle opening.

Step 9: Find some clear space outside. Place the bike pump over the air hole in the cork and have a grownup flip the bottle over, holding the rocket so that the nose (cone) is pointing up and away. 

Step 10: When ready, use the bike pump to build pressure in the bottle. After a few seconds, the rocket will blast off into the air!
