Rainbow water

One of the mums I know switched me on to this fun game. We have a load of old plastic tupperware containers that have lost thier lids and some empty water bottles that were going to be recycled, so I got the kids out the back in the yard and filled all the water bottles up from the tap and dropped a couple of drops of food colouring in each. They had great fun pouring the coloured water back and forth mixing the colours and when they ended up with brown water we watered the plants with it. No stained clothes from the tiny amount of food colouring either.
