Let’s make it

I’ve been trying to cut down on my use of plastic recently but we were given some things in ziplock bags so I thought I might as well try and get a second use out of them! The shamrock shape was drawn on with a Chalkola pen although I’ve made similar using Sharpie pens previously.

Next is do add a bit of blue and yellow paint, I found that you will need a bit more yellow than blue for this.

Once you have added your paint make sure that you close the bag! For younger kids you may find that you wish to sellotape the bag closed additionally. My daughter who is four played with this and was fine just being told not to open it but I’m not sure she would always be able to resist opening it for a play!

Mix the two colours together until your shamrock turns green.  As well as teaching about colour mixing using a squish bag like this can be a good way to practice mark making or letter formation – how about a letter S for shamrock?
