Really Cool Science Projects for Halloween

Updated on July 26, 2012

Halloween Pumpkins


Cool Science for Halloween

We have 30 days left before all Halloween. So I am searching the Internet for new projects for my readers. There are all kinds of cool science projects for Halloween that are not only educational but entertaining as well. If you are like me you are always trying to balance education with entertainment or atleast add education back into your household at all times.

Halloween is one of my favorite Holidays of the year. It is also know as the All Saints Day in Italy. So when I have the cash I love to do it up right. And if I can add a few Science lessons I am even more thrilled.

Tonic Water Does Glow

I have actually used tonic water and made green gelatin glow for Halloween before with my son. I also had tonic water ice cubes so this is an easy touch to any Halloween party that is quite enjoyable. The tonic water ice cubes should be used sparingly though as they change the flavor of your drink. I put them in Mountain Dew to make the Mountain Dew glow in the past.

Glowing Pumpkins

Although I prefer to go for more of the traditional pumpkin I have used the glow powder to make on skeletons and bony hands and other things during Halloween.

Dry Ice

I live in Florida and therefore I always know where there are supplies of dry ice especially during hurricane season. This is a particularly useful skill just before Halloween. And while dry ice is readily accessible if you know whether to look for it , it can be hazardous to deal with if you are not experienced. So I would suggest you use a great deal of caution when using dry ice.

My Favorite Science Project for Halloween

Of all of the Science Projects my favorite would be the Oozing Pumpkin. My suggestion is to use a plastic Pumpkin and rerun the gig as people walk up to the door. I like to set up a proximately alarm (I like a reed switch) that would cause the pumpkin to over flow. You could also do the exact same experiment with the dry ice, water and laundry deter and there would literally be no clean up. You would just have to make certain no one could get hurt with the dry ice.
