Homemade Waterbeads (100% edible)
This is a fun sensory activity for the kids and is really easy to make.
All you need is large sago pearls, water and you can also add food colouring, like we did, if you want to. Sago pearls may not be in your local supermarket but are easily found at Asian grocery stores and are very inexpensive.
Prepare sago as per instructions (just boil them up for a few minutes until plump, omit the sugar if it's listed) and then pop them in some cold water with the colouring. You're ready to play!
You can use them in a tub or even in the bath.
