Thanks MJ.Good work on the science mate!
If you've got some tarnished silver or silver plate, put some alfoil in a bowl, put the silver on top of the alfoil, pour in just boiled water and add 2 tablespoons or more of bicarb soda.
Watch the fizzing that takes the tarnish from the silver to the alfoil.
When it's finished, rinse off the clean silver and show the kids the tarnished alfoil.
Don't put hands in the hot water!
