Grate or peel a white wax candle. You will need about 1/4c wax.
Grate or peel some crayons. Choose some nice colours that will go together.
Pour some boiling water into a bowl. Sprinkle the white candle shavings onto the water and watch in awe as they melt and form a smooth layer of melty wax floating on top of the water.
Sprinkle the coloured crayon shavings onto the hot wax. Swirl them around a bit as they melt to form pretty patterns.
Dip and roll the egg in the hot wax. You can re-dip them as long as the wax is still liquid. Leave to dry.
