It was a cosy and rainy day around the house so I thought it was the perfect opportunity to do a little activity with the kids. Now don't be thinking I do this kind of activity every day or anything!! But sometimes time and energy and creativity collide and this was just one of those special occasions ;)
I had seen a friend post some pics of 'milk colour swirling' paintings she had done with her kiddos on Facebook - mixing food colouring in milk with straws then dipping paper into it to make prints - I remember doing this when little! So I had tucked that neatly up my sleeve to do with the kids 'someday'. When I googled it to see if I needed to do it any way in particular, I came across this awesome blog/idea which took milk painting to a whole new awesome level - and made it a bit of a science experiment too!!!
According to this nifty little blog, you could dip a toothpick into dishwashing liquid then into the milk, and somehow magically it would disperse the colours around it. I didn't even understand how that could work but was keen to try it out....
I gathered two eager little ducklings (whilst the littlest ducky was napping) and a few supplies. I love when you spontaneously do something fun with the kids and with no planning it all, it takes just two minutes to gather the supplies from around the house. It sure does not always go so smoothly but lovely when it does! Seriously - you can try this yourself and it's so easy because you probably have everything you need right in your kitchen and cupboards!
Lily and Eli were so excited to try out our experiment/art project! And I took a lot of photos 'cos it was just all so preeeeeeeeeetty :)
|We poured about a centremetre of milk in the trays. A few drops of colour (the kids chose what they wanted) and then|
they opted for some straws to disperse the colour....
But then we decided to try out this crazy toothpick idea! The kids dipped the tip of a toothpick into a little ramekin of dishwashing detergent and then dipped the toothpick into the midst of their milk and food colouring drops. To be honest I really wasn't sure what would happen or if it would really work but lo and behold to our absolute wonder and amazement.....
Cool, huh? Within seconds, the colour would start radiating out. Lots of 'ooohs' and 'aaaahs' were heard!
The technical explanation is 'The reaction of the soap disrupts the surface tension of the milk causing the colors to radiate away from the toothpick'. It is such a great mix of art, science and fun!! The kids loved 'experimenting' and I was pretty much mesmerised by the pretty swirling colours and was actually itching to do it myself (must get my own tray next time!!).
Now enjoy some more pretty :)

A super fun, easy, creative, beautiful scientific experiment - yup, let's call that a successful rainy day activity!
