To decorate Easter eggs with food colouring you will need...
Hard boiled eggs (or blown out ones)
Spoon (or wire)
1) Mix about 20 or so drops of food colouring with 1 tbsp of vinegar and 1/2 cup of tepid water.
2) Repeat this step with different colours to create a rainbow (recycle tip: use clean, used, coffee cans to hold the mixtures - then you can trash them).
3) Using a spoon (or my friend once made an egg holder with copper wire) lower the hard boiled egg into the colour mixture. The longer you leave the egg in the more vibrant the colour.
4) Pat the coloured egg dry with a paper towel.
Remember: food colouring stains so break out the art bibs.
