Caption Contest, boy dumping water from roof

Welcome to another caption contest! It’s been a while, so let’s go over the “rules”. (Don’t worry, there’s no legalese / fine print here.)

1) Say something funny and/or random about the picture.
2) Keep it clean and family-friendly.

That’s it!

Here are some tips: What are the people thinking (before or after)? What might they say? Why did this happen? What might happen after this? Also remember that you can create circumstances however you want. You could also speak from the point-of-view of a narrator or anyone else you think up. It doesn’t have to be realistic, either — you could imagine it as part of a movie. Basically, anything goes as long as it’s funny and clean. Have fun!

Let me also add that comments continue to get added, so check back occasionally. There’s a Recent Comments section in the sidebar, or you can also subscribe to the comments for a post to receive them by e-mail if you prefer.

creating an explosion on the Moon

I saw where somebody searched for “explosion on the moon” and found this blog, which we have talked about so that’s not surprising.  But I was curious if there was a specific explosion that someone is searching for info about.  So I did a quick search and found several links about asteroids / meteorites crashing into the Moon, which has happened countless times.  But then I saw a link where NASA was planning to trigger a massive explosion on the moon to search for ice.

NASA is preparing to launch the Lunar Crater Observation and Sensing Satellite, which will fly a Centaur rocket booster into the moon, triggering a six-mile-high explosion that scientists hope will confirm whether water is frozen in the perpetual darkness of craters near the moon’s south pole.

Flying a rocket into the moon at 5,600 mph to create an explosion is cool!  Where do I get that kind of job?

Actually, since nobody owns the moon, technically it wouldn’t be against the law to create your own explosions on the moon, right?  Of course, that would require money and technology we don’t yet possess, but we can dream, right?  🙂

boiling water, freezing air, & thundersnow

If you take boiling water and toss it into the air when it’s -22 degrees outside, it evaporates into steam before it hits the ground.  Here’s a video of it.  Looks neat. At first it looks like it’s instantly turning into snow, but it’s in fact steam.

I remember hearing that hot water can actually freeze faster than cold water.  Turns out that’s only sometimes true — according to science, water at 100 degrees C will freeze before water warmer than 60 degrees C but not before water cooler than 60 degrees C.  Although if you put hot water and cold water in the freezer at the same time, the hot water can freeze faster because the bottom part of the hot water can start freezing while the top is still warm (and no convection is occurring).  Further explanation is beyond the scope of this article, but you can read more here if you’re feeling particularly nerdy today.  (It’s actually called the Mpemba effect.)

Also on the page right now is a video of Jim Cantore of The Weather Channel getting surprised by “thundersnow“.  It’s basically just thunder and lightning, but it’s more rare in a snowstorm.  His reaction is interesting, which is why this video has been making the rounds on TV.
