Heebie Jeebies presents the Slime Test Tube Lab! Just add water, and mix to make your own coloured slime! It's that easy. Add 220ml of water to the slime powder, and the polymers in the powder will start to link together. When enough of the molecules get hooked together, the solution turns into slime! A simple and awesome experiment for kids that is easy to do. A gross, slimy experiment that makes for a fun sensory experience boys and girls of all ages will love. Stretch it, snap it, squish it, knead it - its loads of fun. Available in pink, red, blue, green and yellow. Collect them all!
