Building viruses with toothpicks

This is a fun activity designed to teach kids about virus basics and should be adaptable for older groups and other uses. I have run this with a short "Host Range Game" at the end that relies on the colors used for the toothpicks. Downloadable instructions are available here. Please feel free to use or adapt these materials in any way you like.
