Today Mummy made me some petri dishes. These are a jelly made from Agar which comes from sea weed. There is also food mixed in which is sugar and gravy. Bacteria and fungi like this food and jelly and they grow into big lumps called colonies so I will be able to see them.

I tried putting my foot on one petri dish and I took swabs by rubbing cotton buds on my bike helmet, computer keyboard, bin lid and the taps. Now I have to wait for the bacteria to grow.
