You'd basically get wet in the bathtub or shower, and walk around on the bathroom floor so I can see and hear the sneakers squishing. I'd have you do other things like turn the socks inside out, pull down the backs of the socks underneath your heel to make the socks look shorter on your feet, and take the sneakers off, fill the sneakers up with water, and put them back on so the sneakers make a huge squish.
