The science experiment called Instant Worms is very fun. I don’t remember the exact directions, but I do know that you need all the parts that the kit comes with. I also know that if you want the worms to look cool, you need to get food coloring.
The directions explain how to use the food coloring in the fake worms. There is a solution that you have to make. All the resources that you need come with the kit. [The directions tell you how to make everything]
After you make the solution, the kit comes with a goo that you pour into the solution and BAM you have an instant worm.
Great for group activities!
