I am a primary science presenter and teach KS1 and 2 science. Often I am approached with amazing questions thought up by 7 year olds. One of these questions has me baffled and I wonder if anyone can help When explaining molecules I was asked what is inbetween molecules? We were discussing solids, liquids and gases. Myself and my collegues have been thinking about this for a while now and are unsure? It can't be nothing! Physically it can't be a vacuum, can it?? Any Ideas??

I was listening to the radio and they were talkingabout a frequency to deter children from loitering, is this the same??
