First, save some egg shells, I tried to break the eggs in a way to leave one side slightly larger to accommodate the candle. I used a knife to try and get the right size and make it as clean a break as possible and no eggs were wasted, we used them all. I then gave them a quick rinse out and left them to dry.
We put the egg into an eggcup to steady it and to stop small fingers from accidentally crushing the delicate shell. If you choose to you can neaten the edges of the shell with some scissors but we decided to leave them.
Next we used colourful candle sand so that we did not have to use hot wax, this is available at craft shops or you could use wax beads as an alternative if you have some. Aim to fill the egg shell about half or two thirds full, my children decided to fill the shell right up.
Next is the cheating bit, everyone who has small children will have lots of these laying around in the back of the candle drawer, well if you are anything like me that is. Half used birthday candles make excellent emergency wicks, just push the candle down into the wax sand until just the wick is visible. You could use wick if you prefer but I was thinking of the simplest thing for small children.
This is what the finished multi coloured candles look like, you can't see the birthday candle at all, I think they look quite beautiful and it was absolutely safe for small children to make.
As you can see they look lovely alight too...
