This summer we love to spend a lot of time outside. I’m always on the hunt for activities my kiddos will enjoy while I garden or so some work outside around the yard.

This colouring fizzing ice cube activity is perfect to keep little kids and big kids alike busy.

This activity combines baking soda, paint and water to make frozen ice cubes. Adding a squirt bottle of vinegar makes for tons of fun outdoors or in!

This is the perfect activity to do outside to the mess is minimal. I also love that the smell of the vinegar dissipates outside! However, if the weather is not great, it would be easy to do this inside as well. Just use a bin, or even do it in the sink! It will be just as fun, and not too messy.

This fun and colourful activity will strengthen little hands by squeezing the squirt bottle. Meanwhile older kids can learn about acids, bases and chemical reactions. And every kid will love the colouring fizzing fun!

    1. I had no trouble with this experiment, but it would depend what kind of driveway/sidewalk you have. If you’re concerned, I would stick with washable paint and spray the area down with a hose after the activity. In my experience, the sun does a great job of bleaching out any residue very quickly. You could always test a small corner to be sure. 🙂
