Why can we see through bubbles yet they still cast a shadow?
Try this for yourself, it is really weird.
A shadow is caused by light being blocked by an object, right? And we see things because light reflects off of them and into our retinas. So why are bubbles transparent (or glass, for that matter) yet they still cast a shadow? This works in and out of water, so light refraction isn't the answer.

[quote][b]Posted by:[/b] HALOBUZZFREAK 4 I've always wondered if a completely invisible object would cast a shadow. For example, a person with some type of armor/cloak that you could see through. He's still there, you're just seeing through him. Does he have a shadow?[/quote]No. If something is completely transparent, all light passes through it, and no shadow is produced. Fun fact: If a person is invisible, he or she is also blind due to light not being able to focus on his or her retinas. (Thanks, Cracked.)
