Ok, my greatest MacGyverism is probably last time we had a show with my choir. We were supposed to sing "Cabaret" from Liza Minneli, and the 40 of us would wear a hat. The problem was to give each one of us a hat in the 1 and a half minute we had between "cabaret" started and the former song finished. And I do not tell you about everyone finding his spot and position on the stage. It had to go FAST!:o
We tried to make it organised, that 8 persons would take responsibility for sending 5 hats to others. But then, some people got 2 hats, some did not get any, it was a mess...
For me it was obvious, the hats had to come from the roof and down over each of us, so that we could grab our hat and run to our spot.
Then, I fixed 2 long bars over the stage, with a mechanism to get them down and up fast and safely. So was the problem to attach the hats there in a way that would make it possible to have them there from the beginning of the show without them falling, and to grab them without people having to remove anything or taking the risk of damaging the hats: we had to use them for at least the 5 shows + all rehearsals.
So I used curtains rings with a clip on them, and in the clip I attached a magnet. I had to sew a little metal piece on each hat, and then it was done. It worked.
The first evening, we all stood with our backs to the public, in position for "Cabaret", ready to grab our hat. We could hear the public holding its breath when the 40 hats came down, it was just fantastic! And now the choir is expecting GREAT things from me for the next show in January
