A novelty ice cream idea that was a big hit with youngsters in the 60's and 70's was the Tonibell Miniball - a plastic ball filled with ice cream. To tuck into the contents you removed the lid, and when the ice cream was all gone you just snapped the lid back on, then you could have a game of football, tennis and so on, with it. They were sold in various colours and they came with a flat wooden spoon. This advert is dated June 1968 but I can recall when I was at Craigie High school in 1970-74, the 70's ones had either a gobstopper or bubblegum inside as an added extra feature. Needless to say we had many games of football in the playground with them too.
I've no idea when they stopped selling them, I don't have any memory of having ever seen them after my school days, but they were popular in their day, and one of the rare occasions when kids didn't get in trouble for playing with their food!
