Spooky Expanding Ghost

Spooky Ghost (4)

Your little one will get a kick out of watching the spooky-not-scary ghost puff up in this experiment, a trick made possible with good old vinegar and baking soda. It might not be quite as impressive as flaming ghosts, but is sure to earn a giggle.

First we gathered our materials, and I drew two ghost eyes and a big ghost mouth on an uninflated white balloon.

Have your child carefully help add 1/2 cup white vinegar to an empty plastic bottle; set aside.

Next, fill the balloon with 1 tablespoon baking soda. A funnel is your best bet to get the baking soda into the narrow neck of the balloon, but we managed to do so with one adult holding the balloon wide and the other spooning in the baking soda with a baby spoon.

Fit the balloon over the opening of the plastic bottle – don’t let the baking soda fall inside just yet.

When you’re ready, stand the ghost up straight; the baking soda will sprinkle into the vinegar, and the resulting air makes him puff up.

Boo!

Travis loved this so much we went through 3 ghost balloons before the fun was done.
