Coolest childhood toy

What was the coolest toy when you where a kid?
When I was a kid, the incredible crashdummies was my jam.

those Star Trek guns (with the discs)

The G.I.Joe action figures (those 95mm from the 80's to early 90's.)
Me and my brother used to play with them all the time, making up different stories, similar to how some people play DnD roleplaying games.

Many of the stories we played could go on for weeks on end, with the only interruption being eat, school, wrestling training and home chores.

Even though it's been over 20 years since we last played, I can still remember some of the stories we created, and the different personality we gave each figure.
I always hated when my parents told me to clean my room, not because I was lazy, but because, this ment we had to pack everything down.
All the houses, castles and forts we created for them out of cardboard boxes, all the Playmobile houses and cars we had incorporated into our play, the Lego pieces we used to build fortifications with, pillows used as mountain ridges, all for the sake of creating a world for our action figures to wage war.
Sometimes I slept on the floor, because my bed was a battlefield between transformers/He-Man figures and our G.I.Joe figures.

We had to pack it all down, get our mom, so she could confirm, that we had tidied up the room... One hour later we were rebuilding the whole thing.

I miss those years. I still got the g.i.joes in a box, and I do get nostalgic when looking at them.
Occasionally I see some figures for sale in a second hand store, looking as if they were brand new and never played with, whereas mine are all weather, colours faded and limps broken.

I always envied the kids that had slot car race tracks.

I'm so old that all we had was rocks and sticks.

Minibike. I used to give the neighborhood kids rides behind me for 10-25 cents.Girls rode for free as long as they held on tight and were cute.

Also got a chemistry set one Christmas so naturally I mixed together the chemicals they told you not to mix together. Quite a nice test tube explosion.
What did they expect a kid was gonna do?

Water guns, as crappy as they were in the 70s.

@morphyms1817 I always wanted a Super Soaker, but all I had was those weak water pistols without any pressure.
My friends at school all had a Super Soaker.
Man... Those water pump guns could blow your head clean off.
Eventually I learned to use my superior technical engineering skills and my farther's garden hose to compete with them.

I remember one that was transparent blue and looked like a reject from Buck Rogers 1950s, but it was so fun.

Toys during my time were things that you played with. Today, toys play on their own and are tossed in the garbage in about a week. We played with things like playdough and building blocks---you actually had to use your imagination. And toys were built to last (e.g. Tonka trucks). And we played with things that required skill (like hula hoops, jump ropes, pogo sticks, and yo-yos).

Some/a lot of kids still do play with things like that but I wouldn't be surprised if there are some 20-somethings out there who can fly a drone but don't know how to ride a bike.
