ELI5: Explain Like I'm 5

Bifröst

Bifröst is a magical bridge in Norse mythology. Think of it like a really long rainbow that can connect two places together. It's kind of like the bridge you make with your toys to cross over a river or gap.
But instead of just being a normal bridge, Bifröst is made out of colorful light that shines in the sky. Some people believe that it connects the land of humans (Midgard) to the land of the gods (Asgard).

It's also said that Bifröst is very strong and can hold up every god and person who walks or rides on it. But, be careful, because nothing can stop evil spirits from crossing Bifröst.

Overall, Bifröst is a cool mythological element and it's fun to imagine what it might look like if it were real.
