yrobm | Negative pressure/space? | Would it theoretically be possible to create negative space? Say you had a box made of diamond, attached to the most powerful machine on the earth that allowed the box to expand. If you created a vacuum in this box and then tried expanding the box, what would happen? Sorry if this is a dumb question, and I know you can... | askscience | http://www.reddit.com/r/askscience/comments/yrobm/negative_pressurespace/ | {

1kcmaj | the difference between rubbing alcohol (isopropyl) and hydrogen proxide | Aside from the different chemical compositions (are they really that different?), when is it a good time to use rubbing alcohol on a wound vs hydrogen proxide?

xjg4a | Can you catch STDs from a corpse? | What started as a dumb drunken conversation between friends, has turned into a real curiosity, sadly.
If so, for how long is it transmittable? Is it different from STD to STD? | askscience | http://www.reddit.com/r/askscience/comments/xjg4a/can_you_catch_stds_from_a_corpse/ | {
