In my youth there were certain ice-blocks available in the shops: in a plastic& foil-lined paper trapezoidal 5½ fluid ounce container. Three flavours Orange Explosion, Razz raspberry & Glug cola. Haven't seen them for about 45 years. They have made a comeback, same shape & size but this time the metric equivalent of 150 ml. Same shaped package but in plastic this time. No idea what they taste like except it will be quite sweet.
