In this tutorial, we learn how to make slime by mixing corn flour and water. To start, you will need corn flour, water, and two plastic containers. First, pour the corn flour into one plastic container and then add in some water with food coloring to the mix. After this, mix the combination together until it makes a paste. Add more water or corn flour as you mix. When finished, grasp the mix in your hands and it will start to turn into slime! You can color this with any color food coloring, but green looks best to get the true slime effect. This is a fun project to do with children, and is easy and cheap!
