Children are fascinated by bubbles – their colours, the way they float and pop and why do they always turn out round? The following activities are designed to get children exploring bubbles while learning all about shape, size, dimensions and colours – and having lots of fun.


Are bubbles always round?

You will need:
  • Three pipe cleaners per bubble blower
  • Small cookie cutters
  • Bottles of bubble solution
  • A couple of old pots big enough for dipping bubble wands
  • Bend your pipe cleaner into your chosen shape by winding around a cookie cutter. Nothing too complicated – squares, triangles and heart shapes work well.
  • Add another pipe cleaner, passing it through your shape and twisting it into a handle. Twist in an additional pipe cleaner to make the handle stronger.
  • Pour bubble solution into pots, dip in your wand – and blow.

What do children notice about the bubbles? Do the bubbles always come out the same shape, no matter what shape blower they use?

You can explain why bubbles always turn out round by saying that a sphere is the simplest shape nature can make. The bubble liquid makes a sphere because it’s the easiest thing it can do.

For a bit of extra fun, try experimenting with a variety of household objects to see which make good bubble blowers. Some ideas could be a potato masher, a fly swatter and a paper funnel.

    We just LOVE bubbles at our setting – try a rope and make a huge one. We’ve yet to step inside one successfully!

    I’m eager to try out the bubble inside a bubble idea!
