Shrink it is.
Mr Todd began to shrink! his hand slowly shrunk, then his nose shrunk, then his height dropped a little.
But, unfortunately, the shrinking had no effect on his clothing. His glasses fell off his shrinking face, but he caught them, and put them on the kitchen table.
"Oh my!" Mr Todd said, feeling his pants getting baggier, and hearing his feet knocking about in his shoes. "I'm the Incredible Shrinking Teacher!"
He stared around the house as it gradually expanded around him.
He took off his loose shoes and stared at his stripy black and white socks, which also seemed loose on his feet.
"How small am I gonna get?" Mr Todd mused, no sound coming from his mouth.
