What: Eggs and cotton wool dyed with things from our kitchen or garden
How: We boiled three different dye-things in their own saucepans of water, with a little vinegar to help the dye set, added a few eggs to each pan and let them soak overnight (12-18 hours all up). Yellow is turmeric peelings (leftover from some turmeric-lime truffles I made), pink is beetroot peelings (leftover from feeding the kids beetroot!), and blue is red cabbage. We had lots of fun watching the cabbage change colour as we added the vinegar, then eggs (with an alkaline shell), then baking soda to counteract the excess vinegar either Kid 1 or Kid 3 “helped” me pour. The eggs are brown (like almost all eggs sold in Australia) so the final colours have that base, but we also boiled white cotton wool in the water, to put in the egg baskets, and that came out with clearer colours. The cotton wool isn’t something you can keep forever though. Especially the lot that was cooked in the cabbage water – that keeps the odour of boiled cabbage!
- Boiling the cotton wool was good, to see the real colours of the dye.
- Getting to play with the change of colour with the red cabbage was unexpected. We ended up doing that later as another activity – getting all of Daddy’s shot glasses and filling them with cabbage water, then adding various things from around the house to make a rainbow (which I’ll post on another time).
- You could try dying with other things – onion skins are a common one (except the eggs are already brown!). I have dyers’ chamomile growing in my garden but we’ve never collected the shoebox of flowers you’d need for enough dyestuff. Turmeric, beetroot and red cabbage are reliable which is why I used them.
- Lastly, of course, there’s the egg hunt, which was the real reason for doing this project!
