Halloween Science Recipes


Everyone knows Halloween is my favorite time of year. It’s time to blow things up, create bubbling potions and cultivate the “ooze and ahhhh” response. My Halloween parties consist of plenty of green and glowing slime, bubbling dry ice experiments and scary sounds to scare the trick-or-treaters.

If you are looking for the scariest or spookiest ideas for your haunted house, Halloween party or just new ideas for the kids’ Halloween party, I have compiled my favorite Halloween science recipes and videos. Learn how to make a dry ice crystal bubble, get the official slime recipe, or sit back and watch how I carve pumpkins.

This year, my boys and I have also perfected a new way to use dry ice. We call it “boo bubbles – ghostly dry ice.” For the complete instructions on how to make the touchable, smoky bubbles – click here.

My family also loves to have fun in the dark. If you want to do something gross and cool, try mixing up a batch of atomic slime or atomic worms. They are guaranteed to make everyone shiver and squirm.

You can also create a Mad Science Lab with the Halloween Science Kit. It is filled with gross and scary Halloween experiments for a party or use in the classroom.

    I think the CO-2 bubbles might be called “ghost eggs”, because when you break them it looks like a little ghost escapes!!

    Cool idea, I going to try it and see what hatches;-)
