1. Steve Spangler’s Super Slime
The Steve Spangler Super Slime kit lets you create and color your own slime. There are six colors to choose from, including clear glass, hot pink, neon yellow, tangerine orange, radioactive green, and electric blue. The slime is made by mixing a polymer with an activator solution, which helps bond the polymers together into longer chains. The formula doesn’t stain your hands, plus it glows in the dark. Once it dries, the slime turns into slime art—or as I call it, slart. Their formula is designed to reduce bacteria growth. Each kit can make 32 batches. $26.
2. MudWatt STEM Kit
This kit aims to teach kids about energy, electronics, and microbiology by using living bacteria in soil to power a fuel cell. The kit encourages little scientists to experiment with various types of soil, foods, and temperatures to see how they effect the generated electricity. Use soil—any will do—to power an LED and then use the smartphone app to measure the wattage and number of bacteria. The more energy your MudWatt generates, the faster the LED will blink. What’s more, as you make progress, you unlock new sections of an educational comic. $34.
3. LABO
A few weeks ago, we got to test out Nintendo Labo—and it was better than I could have imagined. The cardboard objects you make are fun to build, customizable—I put googley eyes on my car—and make you feel way more accomplished than playing Super Mario for 20 hours. Your creations are made to interact with your Nintendo Switch using both its screen (where instructions and controls are displayed) and the gaming system’s Joy-Con controllers (which you can place in your creations to make them move). This Variety Kit comes with six projects, including a fishing rod, a 13-key piano that plays chords, and a RC car. Pre-order now for the April 20 release. $70.
4. Gross Body Lab
Gross and educational! These experiments teach your child about chemistry and biology by way of craftingbulging eyeballs, gooey boogers, and blood clots. $25.
5. Big Bag of Science
This beastly STEM kit comes with supplies and instructions for more than 70 activities, including creating quicksand, making slime, and growing crystals. It’ll get your kid amped about chemistry, physics, biology, and more. All the pieces come in a re-usable zippered bag, so it’s easy to store your experiments after you’re done. $27.
