Research can be a great thing, but sometimes it can be confusing, especially when we thought we knew things, but actually, it turns out we didn't. There are quite a lot of those, and today, we are going to tell you about 10 Questions No One Knows the Answer To.

We will also talk about dreaming, the origin of life, static electricity, and more. Be sure to keep watching to the end, when we will show you that we still use one piece of Victorian equipment with 21st-century technology, and we don't know why. Thanks for watching, and don't forget to subscribe!
