Much like the scientists at Sanford Lab, we will be investigating and collecting indirect evidence in this activity. Our scientists use indirect evidence to learn about neutrinos and in their search for dark matter. Indirect evidence is essential when investigating something as tiny and hard to detect as a neutrino. Join Deb Wolf for some fun while you "Investigate the Unseen!"

What you'll need: 

• paper towel
• bucket (like an ice cream bucket or wash basin) of water
