Anyone know where I can get one of these cheaply? It's so my DD can do this:

Tts sell them in packs of five for £7 I guess that is cheap as had a look on ebay and the are £13 for 1

We did these earlier this year with plastic jars and pipe cleaners, I used the strong magnets that came with our kitchen cupboard door locks. Any strong magnet will do!
