Sticking a coin with superglue on top of a green steel structure positioned at the corner of a street. Then standing on the opposite side of the street to watch people trying to pick it up. Then me finding it difficult to stand up because I was laughing so hard, and drawing attention to myself at the same time.
Going into town with friends in a shopping area, and all of us standing outside starring high up at a point on a building. Watching people wonder what we were looking at, and then they too would look up. Eventually someone asking, “What are you looking at”, and responding by saying, “We are looking at that brick up there, it looks slightly different than the other 5,000”
Out at night in the dark, me and a friend standing each side of a road, then both of us picking up an imaginary (invisible) length of rope, pulling it tight across the road. Causing all the traffic to stop in both directions. I seemed to have so much power as a child. Or at least right up to the point where we later did it to an unmarked police car. I had never ran so fast in all my life up to that point!
