One of the acts was a comedy strongman/ acrobat/juggler team who kept the crowd thoroughly entertained.
We ended up right at the front of the crowd, so we got to test the nails and check that they weren't blunt or fake. The strongman also dropped oranges on the nails to show they were quite sharp.
The piece of yellow paper was part of the humourous banter - it was intended to make the bed of nails ''more comfortable''.
The strongman's partner went into the crowd and chose a victim to help with the act. This guy had to stand on the strongman's chest whilst the strongman lay on the nails. I always find these things worrying in case the audience member does something unexpected and dangerous -but it passed without incident, thankfully.
When the strongman sat up, we could see the many indentations in his back from the tips of the nails -though no blood or broken skin.
The strongman was also a fire-eater, he managed to produce some huge plumes of smoke and fire.
I suppose he must be used to the taste but the smell of the fuel was really quite pungent.
