I’ve done all 25 and far more. Loved explosives, cannons and home made fireworks.
I did make a kid-carrying kite. Tried it out in a gale. Fortunately the fabric ripped off before I went too far.
Oh yes, same here (all 25 and more). On the hang-glider, I went so far as to meld plastic to a sheet by using an iron and wax paper, which worked pretty well. I was up on a precipice getting ready to jump, lost my balance and the whole contraption fell straight down (no glide), hit the ground and split in two. So seeing that, I decided not to re-build and try again.
As a teenager in Brooklyn, in a neighborhood where houses were fairly close to each other, one of our favorite past-times was roof-hopping, which is self-explanatory.
LOL!
You just reminded me. We used to like to try to build homemade rockets.
After enough launchpad disasters, we figured out it was more fun and much easier to just build small bombs. (Good gawd, could you imagine that in this day and age?)
when my boys were young, their father made a 7 foot kite out of newspaper and moulding....once he got it up in the air it could lift the boys off the ground slightly, they loved it...It finally went down and they had to go looking for it. Found it actually about 1/2 mile from the house..we lived in a sub-division.
