I had an uncle who did a "helicopter ride" for me and the other children, which was scary but amazing, and we kept on asking for him to do it again! I was about seven at the time. We "the passengers" would be shown a toy helicopter, and be told we'd have to be blindfolded, be a bit brave, and use our imagination a bit. We'd be taken one by one into another room for this ride, with my mum and aunt also there. When it was my turn, he got me to stand on a chair, asked me who I wanted to blindfold me: I chose my mum.
He'd put my hands on the shoulders of my mum and aunt, who were now standing beside me. He'd announce "we're going up!", and I'd feel the shoulders moving downwards, and also the chair rising into the air, and I would hear a commentary: "Oh, we're above the fields now, look at those tiny houses, we're flying over London now," and I remember that I felt as if I was really high up!
He'd say "now we've gone so high, we're touching the sky", and I felt something touching my head. Then he said "now we're going down: you can either come down slowly, or you can be brave and jump off the chair, you'll be quite safe". So, as I was told, I jumped off the chair, and it felt like I was jumping miles, like jumping off a high diving board!
It was really scary, like a fast waterslide or rollercoaster. I found out later how he did it: that my mum and aunt would crouch down while my hands were on their shoulders, they would all lift the chair only a few inches, but as I couldn't see it felt like it was really high up. As for touching the sky, a book was gently lowered on to my head!
