I have a question. I am doing a science project on insulative cups I would like to know what is the better insulator plastic or metal? 

Shouldn’t this be what a science project concludes, based on data from testing?

(Some of the best insulators are made of metal, if you can have it enclose a vacuum)

Google the R value of plastic and metal.
