Halloween is the perfect time to do fun Halloween Science experiments like this Grow your own Monster experiment.

Halloween Science: Grow Your Own Monster

Is your family starting to get into the fun and spookiness of Halloween yet?  We have less than a week before the big day!  For Saturday Science today I thought it would be fun to do a Halloween Science experiment and show my boys how to grow a monster.  It’s alive!!

Supplies Needed:

Halloween Science supplies

  • Plastic bottle, we used an empty water bottle
  • 1/2 C Vinegar
  • Tbls Baking Soda
  • Balloon
  • Marker to draw on the balloon
  • Funnel

Step 1: Draw a spooky face on your balloon (Just a note, once the balloon is blown up you will have to draw over it to make it darker.)

Step 2: Use the funnel to pour 1 Tbls of baking soda into the balloon.

Step 3: Use the funnel to pour 1/2 C Vinegar into the water bottle.

 Step 4:  Attach the balloon to the top of the water bottle without tipping the baking soda into the vinegar.

 Step 5: Carefully tip the balloon up and let all of the baking soda fall into the vinegar and watch the creation begin.  Your monster will begin to grow!

Grow a Monster Halloween ScienceSince our Monster’s face faded out a bit as the balloon grew, my 6 year old thought we should draw one on again so he used the marker to make its face darker.

How does it work??  When vinegar (an acid) and baking soda (a base) combine they react and Carbon Dioxide is released.  When you have a balloon on top of the water bottle, that Carbon Dioxide is trapped and it blows up the balloon.  We were surprised that it happened so quickly!  For another fun experiment with baking soda and vinegar, make sure you check out our Easy Baking Soda Volcano.

This is a simple Halloween science project that you could do over and over again.  Are you prepared for Halloween?

And since it is Saturday, I am teaming up with some of my favorite bloggers to bring you the Saturday Science Blog Hop.   I’ve been absent from Saturday science for a few weeks and I’m so excited to be back and sharing these fun science activities with you.
