It was very odd to him that you could take a plastic beaker and you put it in an oven for a minute or two and you take it out and the water is boiling, but there's nothing wrong with the beaker. This he also often used when some of his pals from Robben Island and Pollsmoor came to visit. He'd first take them to the microwave oven when he showed them the house. He'd say, "Look, this is a plastic beaker, I'm now going to put it in the oven," and then he'd put in some water and put it in the oven, take it out and say to them, "Touch it." When they then burned, he'd have a good laugh about it, it was very funny to him.
