If chewing gum doesn't disappear when we eat it, is it really a food?
Jimmy Doherty has a go at making his own chewing gum in his food factory. However, alongside sugar and mint flavouring are a few lesser known ingredients that make up the gum base (polyisobutylene, polyvinyl acetate, wax and talcum powder) - components you’d normally find in inedible products like basketballs, candles and glue. Jimmy melts and mixes all these ingredients together before getting stuck into his homemade chewing gum.
Could be used to encourage learners to reflect on the function of ingredients in food products, and how they are combined to alter or enhance their properties. The individual ingredients could be investigated, with students looking into their source and properties, and how they are used in combination to produce chewing gum.
