Watch a ‘rocket’ take off from the launch pad of your backyard! Do this outside.

To make a miniature rocket you need:

  • a small, thin container with a snap-on lid
  • some vinegar
  • cotton balls
  • a teaspoon of baking soda


  1. Fill the small container halfway with the vinegar.
  2. Wedge the cotton balls into the making sure it doesn’t actually touch the vinegar.
  3. Put the baking soda on top of the dry cotton ball.
  4. Put the lid on the container.
  5. Turn the container upside down, put it on the ground and get away!
  6. Watch the container blast into the air like a small rocket.

Experiment with different containers, lids, and amounts of vinegar and baking soda.
