How to set up this pumpkin science activity?

1. Mix washable paint with a 1-2 tablespoons of baking soda. Mix together till you get the desired consistency. Repeat for each color of paint that you want to use.

2. Place paint on a plate or in a muffin tin.

3. Give kids pumpkins, paint, and paint brushes and encourage them to start painting!

This is a great Halloween art and science activity! Kid can explore color mixing, how gravity works as the paint drips down the pumpkin, and more!

4. Once kids are done painting, give them a dropper (or pipette) and some vinegar! Encourage them to squeeze the vinegar onto the painted pumpkin and watch what happens!

5. Then they can repeat! Paint again and add more vinegar.

Pro tip: Put your pumpkins on a craft tray to contain the mess.

This fizzy science experiment with pumpkins is fun for kids of all ages! I've done fizzy pumpkin painting with toddlers, preschoolers, and elementary schoolers! It's also an awesome activity for a home daycare or preschool!
