Learn a magic trick from YouTube and perform it.

“I didn’t have time to practice with proper soap, so I was going into the performance blind. It wasn’t ideal, but the five minutes were up. I took a deep breath, rinsed out the cup and commenced the magic show. A kind volunteer from the audience offered to be my assistant. She put her finger into the peppery water and thankfully, it didn’t separate. As she was doing so, I put some soap on my finger hidden from the crowd so that nobody could see. This was it, the moment I’d been building towards. I hadn’t practiced with proper soap. My heart was pounding. Would it even work? Would the huge crowd be disappointed? [...] Low and behold, it didn’t really separate. It looked more or less the exact same as the washing up liquid experiment. The crowd was suitably underwhelmed.”
