Five different experiments in an individual test tube:
# Hot Ice Crystals: these form from sodium acetate and generate heat in an exothermic reaction.
# Colour Change Slime: temperature dependant colour change from blue to green.
# Magnetic Slime: responds to the magnet that is included.
# Magic Sand: never gets wet so you can create amazing underwater sculptures.
# Glow-in-the-dark Slime: has special properties that allow it to store light energy.
Each tube is securely shrink-wrapped. Size approx 5 cm diameter at the cap and 15 cm long.
