What a great introduction to polymers!
This pack is a very economical option to produce 24 bouncing balls from 12 moulds, powder and water. Students simply pour the coloured powder into the plastic mould and submerge it in water for one minute to polymerize. Then open the mould and Voila! each student has created his / her own high bounce ball.
