Emily from St. Cloud wants to know what happens to all the sandbags after the flooding is over? If the sand isn’t contaminated with floodwater, it can be used as fill for things like playgrounds and sidewalks. But in most cases, the sand is contaminated.
Brad from Watertown wants to know: Why are there dots on our windshields? Our friends from Abra Auto Body and Glass helped us with this one.

Amerti asked: Why do we associate red with romance? For centuries, red has meant danger, strength, courage and love. It’s always been considered a powerful color that stands out to represent things that are powerful to people.

Riley, the Heine family’s English setter, can sleep anywhere, anytime. So, that had Karen from Edina wanting to know: Why do dogs sleep so much?
