Today I came across an entertaining piece, a scale of the universe, this flash card literally swallowed me up for 20 - 30 minutes. When scrolling with the wheel, you can see how the sizes of visible, and invisible objects of the observed universe are compared. And if you are interested in some object, then a simple click on it you can find out detailed information. For greater effect, do not forget to turn on the soundtrack. Enjoy watching!
