I remember watching this show and working out how to do the cotton thread trick which I fooled my friends after with it. And a few years ago I found the name of this trick is gypsy thread. I always used to watch his shows. Great magician

pity that Michael Allport & Jennifer didn't do their version of Nikola's 'Squeezed to a Jelly', since a TV studio would be one of the few venues with a ceiling high enough for the plunger apparatus.  Might your website be able to track them down from when they worked it on a BBC children's show in the mid-60s, or their appearance(?) on THE GOOD OLD DAYS?
