How To Construct Your Rocket

Before you can make your rocket fly, you have to get it looking good! This is optional, but it makes the project more fun when you personalize it.

  1. Paint or color your toilet paper tube.
  2. Cut a circle out of construction paper, just a little bigger than the diameter of the tube.
  3. Make a cut in the circle to the center of the circle. Then form the circle into a cone to be the front of your rocket.
  4. Put a line of glue around one end of your tube. Gently place the paper cone on it and let dry.

How To Make Your Rocket Fly

This part takes some trial and error. It's a science project so that is to be expected though. Remember to keep trying.

  1. Take your plastic egg and tape up any holes that might be in it.
  2. Put the narrower end of the egg into the open end of your rocket and tape it into place.
  3. Take an Alka-Seltzer tablet and break it into quarters. Put a piece into the other end of the egg.
  4. Now it is time to act fast. Put a tablespoon of water into the bottom of the egg and quickly close up the egg.
  5. Hold the rocket by the bottom egg and watch it blast off!

Notes

Safety

This is a pretty safe activity, but you are creating a projectile. Make sure you never aim it at anyone's face or eyes.

Repeating the Flight

You can repeat this activity over and over. Just make sure to dry out the plastic egg in between flights. You want to use the whole reaction to make your rocket fly, and that reaction will start too soon if the egg is wet when you first put in the Alka-Seltzer.

Experiment

You can experiment so much with this project. Try adding more Alka-Seltzer. Try more water. Try different eggs to see if they separate better.

Involve your children in the problem solving and adjustments you make. Ask them what they would like to change and what they predict will happen as a result.
