We’ve updated our Halloween Science Experiment Collection! Click here for 10 more awesome Halloween science projects, including Frankenworms and Alien Monster Eggs!

Here are two fun Halloween science projects that will amaze and entertain kids!

Mad Scientist’s Green Slime is a homemade polymer that’s as much fun to play with as it is to make.  Send some home with your party guests in zip-lock baggies!

Try making Fizzy Balloons too, but before you do the experiment, draw spooky faces on the balloons and watch them grow as the gas turns them into Halloween monster heads!

Here’s a video demonstration I did on our local morning show.  It will start playing on the right side of the website.  Halloween Science on Kare 11 Sunrise show
