One father started telling his daughter very random yet very interesting facts before bedtime but her curiosity has outlasted his knowledge. So, desperate to keep his little one entertained, Redditor u/ExpiringFrog asked people to share tidbits of interesting things that could do the trick. His post quickly went viral, generating nearly 100k upvotes and over 20.5k comments, with cool facts about pretty much everything you could think of. From guinea pig owning laws in Switzerland to the time it takes a snowflake to reach the ground, I think it’s safe to say that the father is covered with fun facts for kids and adults alike! The best part, however, is that you can enjoy these snippets even if you’re not a little girl trying to fall asleep.
