Step 5: Spray the Dragon's Egg
I have a number of old cans of spray paint and so I chose black (with a red glow at the bottom), half and half gold and silver, and a really rich green.
If you don't have spray paint then any water proof paint will do, household emulsion (called Latex paint in the US), or even nail varnish, (ASK THE OWNER of the nail varnish first, that stuff can be expensive!)
You could try almost any colour. I believe that Dragon's Eggs of almost any real colour have been described and I'm sure there are a few out there with imaginary colours!
Use the edge of a corrugated cardboard box, the prong in the middle of the egg box, some flower arranging foam, or a large bit of Blu Tak to pop the other end of the cocktail stick in to hold the egg while it dries. (how easy is that?!)
