The title pretty much says it all! I use the standard cut and restored rope routine but use a strawberry lace (a type of string shaped sweet if you didn't know) and get the spectator to bite it in the middle, showing two strands, then restore it with their magic kiss/blow.
I like to do impromptu stuff on my friends and strangers at bus stops, pubs etc, so getting out string and scissors would be a bit weird, but having a pack of strawberry laces is much more normal and the spectator can keep the strawberry lace too! It gets great reactions!
Anyone else heard of this being done - I'm kind of curious if I'm the first (I seriously doubt it).
Sometimes I do polo and strawberry lace tricks beforehand too in lieu of ring and shoelace tricks and it gives the whole routine a sweet theme.
