Make one large eyeball and three small glow-in-the-dark eyeballs with this Horrible Science kit! Simply layer the crystals in the moulds provided and place in water for a few minutes. Then bouncy the eyeballs about and scare your friends and family!
The kit contains the moulds, crystals, a funnel and measuring spon plus a Horrible Science instruction and information guide. Please note that the balls will gradually harden over a period of time and no longer bounce.
For ages 68 years and upwards, some adult help may be required.
Just add water!
