DIY of the Week: Bottle Rocket

Looking for something cool to do this summer while your kids are home from school? Check out this fun and easy bottle rocket that you can make using stuff you probably already have in your kitchen cabinet!

** This is an activity for outdoors in a spacious area. **

To make a simple bottle rocket you will need the following:

What you will need.

What you’ll need (or, possibly, the contents of our under-the-sink cabinet).

Bill of Materials:

  • An empty water bottle
  • White vinegar
  • Baking soda
  • Toilet paper
  • A cork

Step 1: Poor about 1 inch of vinegar into the empty water bottle.


Pour vinegar into the empty water bottle.

Step 2: Pour a small amount of baking soda (about the size of a quarter) onto 2 squares of toilet paper. Fold the ends into the middle and roll shut, creating a time release capsule. When you drop this into the water bottle (don’t do this quite yet!), it’ll take a few seconds to begin to react, giving you time to set up your rocket and move away from the launch site so you don’t get bonked in the face with a bottle rocket.

Step 3: Outside, in a spacious area, drop the paper and baking soda wrap into the bottle. IMMEDIATELY cap with the cork. Stand the bottle on the cork and step back.

Step 4: BLAST OFF! Wait and watch. As the paper dissolves in the water, it slowly releases the baking soda, creating a chemical reaction that releases the gas that will power the rocket. You can click here to learn more about chemical reactions! Allow time for the paper to unravel mix the two ingredients, and stand well back from the bottle. On our first try, we thought we had mis-measured and caused a dud reaction, but to our surprise, it went off as we were going to reach for the bottle.

  1. Hmmm…I’m bookmarking this for the 4th of July (fireworks have been banned here the last several years). I bet the kids will love it!
