I love thinking back about many of my childhood toys. I love the memories that are associated with them more than the toys themselves. I remember how much fun I had as a child before life took over with all the stresses and responsibilities. There are a few of those toys that I would still play with love to have. These were one of my favorites and I would spend hours and hours in the summer walking around with them.
The ones that I had were called Knicker Knockers. However, after doing some research, they have also been called: Bangers, Bonkers, Clack Clacks, Ka-Bangers, Ker-Knockers, Klackers, Klick-Klacks, Knockers, K-Nokkers, Mini Poppers, Quick Clacks, Quick Klacks, Quick Wacks, Popper Knockers, Poppers, Rockers, Super Clackers, Wackers, Whack'os, Whak Kos, and Zonkers. By looking at some of these names, you can see how things have changed over the years as some of them could also work as a title of an, um, adult movie, if you know what I mean. Yikes!
I had two of these that looked a little different than the picture. Mine had a plastic piece to hold onto instead of the hoop at the top. You would hold onto the top and move your hand up and down. The goal was to get the plastic balls to hit each other at the bottom, swing up, and then hit each other at the top. The trick to get them to hit at the top was to move your hand fast enough to gain some speed. Once that happened, you would just continue to hit them together. I could sometimes go on for minutes at a time without stopping.
I loved these things! However, let me also just say that this was the most dangerous toy I ever owned. Try tying a rock to a string and whipping it around really fast and see what happens. Those hard plastic balls on the end could give you a lump on your forehead the size of a golf ball. I remember hitting myself in the face, chest, arms, and hand. But the worst spot to get hit was the wrist bone. Ouch! It hurt so bad, I would see stars. I wish I would have been a smart kid and thought about using protection. This would have come in handy!
So, what would I immediately do after whacking myself and able to catch my breathe again? Well, I'd start banging them around again, of course! I was a slow learner back then and it took about four blows to the wrist before I would decide that I had enough pain and put them down. But sure enough, the next day, I would pick those bone crushers up again and start the process all over again. For some reason, they were worth the pain.
I really wish I had these today. I would carry them around instead of a can of mace and use them to knock someone out if I had to.
