  2. Now get your kids to wash their hands.

  4. Next, ask your kids to add a couple of gentle sprays of water into each bag using the spray bottle.

  5. Zip the bags closed and pop them on a shelf or inside a cupboard. Be sure they are out of reach of your kids.

  6. Every few days check the bags. Your kids should be able to see which one starts to grow mould quickest.
