Mould it, stretch it, snap it, ooze it! This gooey science kit is packed with fun activities to do with freaky fluids. Mix coloured putty to make new colours and add glitter to see it sparkle. Build a scary putty monster and watch it slowly flow until it is a puddle of gunk. Create shadow shapes in glow-in-the-dark putty and use body heat to change the colour of thermochromatic putty. Mix up some cornflour slime and play with its crazy solid and liquid properties. Roll it into a solid ball and then feel it flow between your fingers.
