This is an application of Lenz’s Law and there have been a number of effects based on this phenomenon including the beautiful Mystic Tubes of Sea-Ling by Richard Gerlitz and Paul Green’s comedy presentation: Field Sobriety Test.
However, for my money, if you want to perform the effect this is the best version. This routine is structured so each phase builds until you are convinced that that the moon rock is real and magical. This is a great example of how a good routine can transform a simple science experiment into full on wizardry! The belief is aided by the beautiful props that are solid and look genuine as you have come to expect from Wellington Enterprises.
There is a simple switch involved but because the routine is so well structured you’ll have plenty of cover and if you want to perform this you’ll quickly master it even if you avoid other effects that require a switch.
These are now getting hard to track down, but well worth the effort if you like creating miracles 🙂
