Researchers in Belgium have figured out why apples stay crunchier, after being picked, than pears. Micro structures through out the fruit of an apple are able to deliver oxygen to the cells while the structures in pears are dense and closed off which prevents oxygen flow. These scientists determined this by using a high tech radiation facility to create images of the internal structure of the fruit. But, you can get a sense for their findings yourself at home. Drop and apple and a pear in a jug of water. Find out which on sinks? Can you think why?
