Halloween Science Experiments

Exploding ghosts, ghost bombs, expanding ghosts oh my!  These experiments are perfect for kids and kids at heart!

Exploding Peeps Geysers 


You will need:

  • Empty plastic bottle 
  • 3 Peeps
  • A Microwave

What to do:

Cut a few inches off the top of the bottle so it will fit in the microwave.  Squish your little peeps into the bottle.

Ask your kids what they predict is going to happen when you microwave the ghosts. 

Place your peep-filled bottle in the middle of the microwave.  It will only take about 30 seconds before the explosion is over so be ready.  The peeps actually fly out of the bottle. How cool is that! 

Just like regular Marshmallows, this sticky pile became hard as it cooled.  Surprisingly it was not all that hard to clean up.

Ghost Bombs


You will need:

  • Hollowed out eggshells 
  • Black marker 
  • Corn starch or baby powder  
  • Tissue paper 
  • A glue stick

What to do:

Begin by hallowing out the desired amount of eggshells.  To do this gently tap a butter knife on the surface of the egg to create a hole in the shell.  Then, pour the yolk into a bowl.  Rinse the shells under warm water with a bit of antibacterial soap, and then allow them to dry.

Once dry use a sharpie to draw ghost faces on the shells.  Then, fill them with corn starch.  You can also use baby powder.  How much powder you put into the eggs will affect how they smoke when thrown.  We filled them with varying amounts to create different ghostly effects.


Once the eggs are filled carefully seal the tops by placing tissue paper over the openings.  To do this cover one side of a tissue-paper-square with glue, and then gently press it over the egg opening glue-side down.  That's it! Then, it's time to go outside and throw your ghost bombs!

Spooky Expanding Ghost


You will need:

  • Empty water bottle
  • Balloon
  • Small funnel
  • 1 Tablespoon baking soda
  • 1/2 cup vinegar
  • Permanent marker

What to do:

Pour 1/2 cup of vinegar into an empty water bottle.
Draw a face on your balloon if you’d like while it’s deflated.
Place the funnel into the open end of the deflated balloon and pour in the baking soda.
Secure the open end of the balloon onto the top of the bottle being careful not to dump the contents of the balloon into the bottle quite yet.
When you’re ready, hold the balloon upright allowing the baking soda to fall into the bottle and mix with the vinegar.
