Imagine you’re headed to your attic to retrieve a box of old family photos, or mannequin heads, or your anarchist manifesto, or whatever it is you keep in your attic. While searching, you glance at the wall, and there’s the gnarliest Spider you’ve ever seen. It’s huge and multicolored and looks like it’ll kill you with one bite.

Then it bites you. Now you have to identify thw Spider so you can find some antivenom. But you’re no arachnologist, so your ass is grass.

Or it would be, without the Internet! Because chances are, there’s a community of Spider experts on a website like Reddit. All you have to do is post a picture of the spider and they’ll probably know what it is. Even better? It’s not just for spiders. It works for anything!

The Internet makes it easier to identify the wild and weird stuff we all see in the world. Here are 15 times when someone asked the Internet to identify something strange, and the Internet delivered. (via Bored Panda)

14. My girlfriend found these in her dinner? Are they seeds?

Answer: Pretty good picture of insect eggs.

15. Anyone know what those round impressions are called, and what are they for?

Answer: Old windows were made of glass spun out into flatness. That’s the center of the spin.

New windows are made of glass floated on a pool of molten tin, which makes very flat panes without any annoying bullseyes.

EDIT: this is also the source of the myth that glass is a liquid and flows over time. See the center pane of your picture? Someone took the time to get a “good” pane for the center of the window, without any bullseye – put your best pane in that spot, obviously. But the glass is still of uneven thickness, getting thicker closer to the bullseye. So people look at panes like that, with thicker glass in one part, and decide that “hey, the glass must have started off perfectly flat and flowed over time”. But no. The glass flowed when it was molten (1500 degrees C!) and does not flow at room temperature.
