Slime has been a big hit with kids, but what if I told you there are science projects better than making slime? *Gasp!* It’s true! And, believe it or not, they might even learn something and have fun in the process. Trying to convince kids to be interested in science can be tough, but we can do much better than slime.
It just creates a mess and wastes valuable laundry detergent in the process. Sure, it’s easy to teach and easy to make, but that’s about it. Thankfully, there are plenty of easy science experiments you can teach your kids with things around the house, and none require detergent to do it.
Plus, I’m willing to bet these projects will be considered much cooler than slime. So, get your lab coat on, and get ready to learn about these 15 Science Projects Better Than Making Slime.

Homemade Ice Cream
Teaching kids about science doesn’t always have to be gross or boring, it can actually have a tasty result. To do this experiment, you’ll need 1 tablespoon sugar, ½ cup milk, cream, ¼ teaspoon vanilla extract (or other flavoring), 6 tablespoons salt, ice to fill the gallon-sized bag halfway, 1 gallon-sized Ziploc bag, and 1 pint-sized Ziploc bag.
Larger salt crystals work much better for this experiment. Add the salt and ice to the gallon-sized bag and the remaining ingredients in the pint-sized bag. Add the pint-sized bag to the gallon-sized bag, seal it, and shake it for five minutes. By the end, you should have delicious ice cream.
Pop Rocks Expander
Who doesn’t love pop rocks? With this science experiment, you’ll need a 20 oz bottle of soda, a packet of pop rocks, a balloon, and a funnel. Place the funnel inside the balloon and pour the pop rocks into the balloon.
Then, wrap the opening of the balloon around the open soda bottle. When you’re ready, lift the balloon to drop the pop rocks inside. The balloon should inflate.
Steve Spangler's Jelly Marbles
These amazing beads absorb over 300 times their weight in water.
Once you pour them into a bowl of water, it looks like they vanish. Take them out of water, they’ll dry out, and you can use them over and over again.
Growing Rock Candy
This project is super easy and will, of course, taste sweet once you’ve finished it. Keep in mind, it might take up to a week to complete. I know, that’s a long time to wait, but it’s worth it. To do this project, you’ll need 1 cup water, 3 cups table sugar, a clean glass jar, a butter knife, a string, a pan or bowl, and spoon.
Tie the string to the butter knife and place it over a glass jar with the string hanging inside without touching the sides. Boil the water, stir in the sugar, and if you want colored rock candy, put in a few drops of food coloring.
Pour your sugary solution into the glass jar and perhaps cover it with a coffee filter so no particles get inside. Keep checking back each day to see if sugar crystals are growing.
If your students are aspiring secret agents or just want a way to pass secret notes, this easy invisible ink solution will certainly blow their minds. You’ll need lemon juice, water, a spoon, a bowl, a cotton bud, white paper, and a lamp.
Squeeze lemon juice into a bowl, add a few drops of water and mix it with a spoon. Dip the cotton bud in the water just slightly and use it to write a message on the paper. Let it dry and then show your students the message under a lamp.
