Resources

500ml drinks bottles. Socks. Elastic bands. Scissors. Tray. Washing up liquid - lots of it!

Instructions

Remove lids. Cut bottle near base to remove the end. Over this cut end, stretch a sock or square of sock fabric and secure with an elastic band tightly around the low indentation of the bottle. On a tray have lots of washing up liquid ( very very very slightly diluted ) . Dip the sock in the solution then blow through the neck of the bottle. A worm of suds should appear from the sock.
Have lots of clean water around in case the cubs get washing up liquid in their mouths. If they do, they learn quite fast not to!
