You’ll need:
- Warm water
- Large unbreakable container with a lid
- Straws, wands
Mix up a batch of bubble stuff and store it in the container. Try different combinations of liquid to soap until you have something you like. If you add a little glycerin and a pinch of sugar your bubbles will last longer. Here's another recipe using corn syrup.
Experiment with drops of food colouring to make coloured bubbles.
For fun giant bubbles make a large wand out of a bent coat hanger.
