DIY Lava Lamp


  • Clear plastic bottle
  • Water
  • Vegetable oil
  • Alka-Seltzer tablets
  • Food coloring


  1. Fill the bottle one-third full with water.
  2. Add vegetable oil until the bottle is almost full.
  3. Drop in a few drops of food coloring.
  4. Break an Alka-Seltzer tablet into small pieces and add them to the bottle.

  • Lamp or heat source


  1. Squeeze lemon juice into a small bowl and add an equal amount of water.
  2. Dip the cotton swab into the mixture and use it to write a message on the white paper.
  3. Allow the paper to dry.

When you’re ready to reveal the secret message, gently heat the paper near a lamp or light bulb. The acid in the lemon juice will react to the heat, making the message visible. This experiment introduces kids to the fun world of acids and bases.

Static Electricity Butterfly


  • Balloon
  • Small piece of tissue paper
  • String


  1. Blow up the balloon and tie it.
  2. Cut out a small butterfly shape from the tissue paper.
