Here's a fun science project to do on Sunday before you toss your jack o' lanterns to the squirrels: DIY Puking Pumpkin!
Step 1: Sprinkle some baking soda in the bottom of the jack o' lantern.
Step 2: In a glass mix a healthy pour of vinegar, some glitter and a few drops of food coloring.
Step 3. Place the jack o' lantern on the edge of the sink and pour in the liquid and watch poor Jack puke his guts out.
Enjoy much squealing and delight!
