Science can be silly and strange. The library has entertaining books about grossology, the science of really gross stuff. Try making icky slime at home, with some help from your parents. You will need: water, food colouring of your choice (I chose green), and cornstarch.

Step One: add a few drops of food colouring to a 1/4cup of warm water and set it aside.

Step Two: pour 1/4 cup of cornstarch into a Ziplock bag.

Step Three: very slowly, pour your coloured water into the bag, seal it, and squish the mixture with your hands (ew, nasty!) If your slime is too watery, add a dash of cornstarch. If it is too stiff, add a few drops of water. Your consistency should be more goopy than Play-Doh.

Step Four: remove your slime and start experimenting; you're an honorary scientist now!

Roll your slime into a ball. The slime will act like a solid, as long as you apply pressure to it. Then, let the slime gently rest on your hand. It should act like a liquid. Scientists call this fluid "non-Newtonian" because of its solid and liquid characteristics. Gross Alert: It can ooze right through your fingers onto the kitchen floor.
