My mind is blown that Snackersmom's avatar is no longer Snacker the ceramic bear, of which came from the devil!
Really though, your avatar now is lovely. Flowers are the best.
My mind explodes somewhat regularly. I'm easily captivated.
Examples:
Texting. How do the words that I type float through the air and get to the other person's phone in that exact order within seconds?
Language. That we understand each other, these symbols, that they mean something and we comprehend them, but any other symbols/languages we aren't familiar with are nothing to us, but clear as crystal to those who are familiar with it...just blows my mind.
Buttons that make cool things happen. Example (an example within an example! Exampleception): My parent's car has a button on the dashboard that makes a little door slide up to store stuff in. You push the button again, and it slides the door shut. I sat there and pushed that button 10 times I'm sure. How does the same button that opens it, close it? Obviously there are mechanics to it but since I don't know what they are my mind is blown.
That there are places on earth that have NEVER had humans eyes see them. Only God knows what kind of creatures are there: in the deep, in the jungles, in the mountains, etc.
