This last reaction is super fast to put together, which makes it a good one. (Learn more about this reaction-> Elephant Toothpaste: A Fun Sensory Explosion)

So feel free to use the easier to get hydrogen peroxide. Yes, the foam will be bigger and thicker with the higher concentration, but it is still pretty great with the lower one. However, I use the 3% hydrogen peroxide you can just buy at Target and it works just fine. This is a stronger concentration than you find in the store, but you can order it online. And the dish soap again helps trap the oxygen to make great bubbly foam.Ī lot of elephant toothpaste recipes call for 6% hydrogen peroxide. It’s called a catalyst, which is a substance that increases the rate of a reaction without being changed itself. The yeast is used to speed up the reaction. This normally takes a long time to happen. The hydrogen peroxide in this reaction is broken down into water and oxygen. This creates a thicker foam that is awesome for kids to play in, so be sure to do this reaction in a bigger container so you can enjoy the result! The Science: Don’t worry, it isn’t hot enough to be dangerous, but do know it is supposed to be warm. This is an exothermic reaction, meaning the foam that results will be warm. Be careful, the reaction will happen quickly! When you are ready for your pumpkin to ooze like crazy add the yeast mixture to the pumpkin. Add a nice squirt of dish soap and the food coloring of your choice. Pour 1 cup hydrogen peroxide into your pumpkin. It will be thick, but mix it as best you can and set it aside. Mix 2 tablespoons yeast with 3 tablespoons warm water.
Yep, this fun foam can be added to your Halloween activities. This oozing pumpkin is courtesy of elephant toothpaste. (Get more vinegar and baking soda activities-> Baking Soda and Vinegar Activities for Kids) The dish soap works to trap the carbon dioxide and create more and bigger bubbles. This gas is what creates the bubbles that ooze out. The combine and one of the products is carbon dioxide.
The baking soda and vinegar are the two reactants we are looking at here. To make your pumpkin ooze with ickiness, pour 1 cup of white vinegar into the mixture in the pumpkin and stand back! Gently make sure everything is mixed well. If you want colored ooze then add a few drops of food coloring. Mix in 5 tablespoons of baking soda and a healthy squirt of dish soap. Take your cleaned out pumpkin and put about 2/3 to 3/4 cup of water into the bottom. This is one of my favorites because it is such a classic. The first way to make your pumpkin ooze uses a classic eruption recipe. I don’t like to make extra messes for myself, so I keep the pumpkins in a container. The eruptions are easy to clean and safe, but they will spread out quickly if not contained. Be sure your pumpkin is oozing while sitting in a container or outside. One final big tip: Secondary containment. Leave a couple of inches for the reaction to start in.) And as I said, these won’t hurt your pumpkins! Just rinse them out and you can still set them out for Halloween night. (Though be sure not to carve too close to the bottom. Carve a design or face in or not, that is your choice. Whatever size pumpkin you decide to use, cut off the top and scoop out the seeds like you normally would. So keep that in mind when you look at the measurements.

(Ben is just finally old enough to have the patience for a full jack-o-lantern.) I have also found that the reactions are more impressive without having to use a ton of reactants. They are cheaper and we don’t always actually carve pumpkins. We used small pumpkins for our reactions. This is the fastest to put together for when you need something fast! It creates a thicker foam that is great to play with. Here are the three reactions we are going to look at: The great thing about these is you can do them over and over! Just rinse out your pumpkin between experiments and try again! There is no damage to your pumpkin. The goal of these experiments is to show your children some easy chemical reactions and of course, add in some holiday fun.
