Smashing Fun!
‘Clankers’ were popular in the 1970’s and were simply two acrylic balls attached to either end of a piece of heavy duty string. The idea was straightforward enough, you tried to get them to swing in motion and ‘clank’ together, then try to repeat this again and again in a rhythmic motion.
When some started to shatter after repeated impacts, schools across the US started to ban the toy, fearing student might get injured. Then in 1976 the US government classed them as ‘mechanical hazards’, which pretty much ended their career as a fun toy.
