Halloween Science Projects for Your Little Monsters

slime-science-a One of the best holidays for kids, Halloween is the perfect time to get your little monsters’ brains ticking.  Masking science with fun makes it even more enjoyable for them.  Check out these scary projects:

Buy a Blacklight

Blacklights are super cool for kids (hippies love them too.)  Switch out a lightbulb with a blacklight, pour some tonic water into a glass, and voila you have a glow in the dark drink!  If you use tonic water for jello jigglers, the jigglers will glow as well. 

Make Your Own Slime

Ooooh slime.  There’s something about icky, gooeyness that children love.  The results is a polymer that contains qualities of both a solid and a liquid.  It can take the shape of any container that holds it, yet you can hold it in your hand like a solid.  Keep the slime in a plastic bag so it retains its properties.

You will need:

  • Elmer’s glue
  • 2 disposable cups
  • Food coloring (preferably green)
  • Borax Powder
  • Plastic spoon
  • tablespoon


1.  Fill one cup with water and add a spoonful of Borax powder and stir.  Set aside.

2.  Fill the other cup with 1 inch of glue.

3.  Add three tablespoons of water to the glue and stir.

4.  Add a few drops of the food coloring to the glue and stir.

5.  Add on tablespoon of the Borax solution to the glue and stir well.  The slime will form.

6.  After the slime forms, let it sit for about 30 seconds and then pull it off the spoon and play with it.

Screaming Cup

A cup that makes an eerie screaming noise!  Your kids can carry these while trick-or-treating for the added effect.

  • You will need:
  • Large plastic cup
  • Piece of string 24’’
  • Water

1.  Poke a hole in the bottom of the cup.

2.  Thread the string through the hole and tie a knot at the end of the string to hold it in place.

3.  Wet the string.

4.  Hold the cup in one hand and pinch the string between your thumb and forefinger.  Squeeze tightly on the string as you slide your thumb and forefinger down the string.  The string will stick and slide between your fingers causing a screaming sound.

Enjoy these projects and have a fun Halloween with the kids!
