I am slowly getting into some summer routines with my kids; which includes spending as much time outside as possible! One activity that we do every year, is making liquid sidewalk chalk together. It is so simple and mixes a bit of science, to create the chalk, and lots of art! I use corn starch and add a bunch a water. It needs to roughly be the consistency of melted ice cream (thicker than water, but runny enough to still squeeze out of the bottle). My kids then added several drops of food colouring into the bottles and then I poured in the white liquid chalk.
I tend to use quite a bit of food colouring. I like the colour being really vibrant and they stand out so much more then regular sidewalk chalk on the driveway. The squeeze bottles are fun to use as something different to create art with and my kids love them, so we use them every summer.
We also tend to bring out a muffin tray and make up some more liquid chalk paint. My kids like experimenting with the food colouring and coming up with their own colour creations. We used thick paint brushes and some small sponges to paint with from the muffin tins.
I love the colours and how beautiful our driveway looks right now. If you have never made liquid sidewalk chalk before, I strongly recommend it. You made end up with kids covered in chalk, but it is well worth it!
