Another question (inspired by the forum discussion on the relative safety issues of different smoke machines)...
A while ago (15 or more years?), I purchased an effect from Cliff Lount's Magic Studio (based in Bradford, UK) called 'Hot Spot' .
I imagine that the effect is reasonably well known - i.e. (stripped down to the bare-bones) - you take a piece of silver foil and tear it into several pieces - each piece is rolled into a ball - and given to a different spectator. The nominated spectator finds that their piece of foil is becoming hot (it really does get hot).
Now, about 7 years ago, I found the bottle containing the material for this effect - but only found a residue in the bottle. I added water, and hey presto (!) - I had a fresh mix of material for lots of repeat performances.
Anyway - fast forward to about 2 years ago and the Blackpool Convention. When I mentioned the effect to Cliff Lount who was there, he was *extremely* dismissive of the effect and said that he would no longer consider marketing it - and that I should have ensured that I'd washed my hands thoroughly after each performance. (As a teenager back when I got the effect, I can't say that I always did this immediately).
So - can someone tell me:
(A) What the dangers were with this material (or even what the material was - if the effect is no longer being marketed - then I guess 'tipping' won't affect things)
(B) If there are other approaches to this effect (other than the 'Bluff and Guff' / 'Hot Coin' -style approach) that are safer? I liked this effect - since it seemed so impromptu - i.e. I just needed someone to be eating a foil-covered chocolate item (e.g. Kit-Kat) and with my hands apparently empty - I was set to go.
(C) When are my fingers going to drop off?
(D) Does anyone want to buy several guitars, card-indexes - and pairs of gloves (in the event of 'C')
