How many bullets did the commando shoot?
Posted by Rhett Allain on June 16, 2010 Somewhere on the internet, I came across this Cracked.com article on movie myths about guns. The article wasn’t too bad, but I really liked this video they included from Arnold’s movie Commando. The myth for this particular clip was that guns never run out of ammo in the movies. Right away, I thought: I wonder…
Do Bikers Cheat?
Posted by Rhett Allain on June 8, 2010 Well, maybe that isn’t the best title. You see, there is this video going around saying that it is possible that a professional bike racer was cheating by putting a hidden motor in his bike. I am not really going to talk about the cheating aspect (my gut feeling says that it would be too…
Spoof Science: Are kids dangerous?
Posted by Rhett Allain on June 4, 2010 I got tired of attacking ESPN Sport Science. Well, tired of attacking might not be the best term. How about, attack in a new way (here are my older Sport Science attacks). Check out episode 1 of Spoof Science: A couple of notes: Watch it youtube if you want the HD version Making videos takes…
How fast was the car going?
Posted by Rhett Allain on June 3, 2010 Reader Colin asked a great question about this popular clip. How fast was the car moving? First, a quick assumption. I will assume that the frame rate on the video is correct (meaning not slowed down). Colin already looked up the length of the Chevy Impala on Wikipedia for me. It has a length of…
Why would I think that?
Posted by Rhett Allain on May 31, 2010 So suppose you saw something that looked like this: This is a ball shot out of a shooter device. Well, it is a vypthon animation of a ball. What would you do if you came to see this video? If I had not made it, I would say it is an unrealistic video. It does…
Tail-Drop Analysis
Posted by Rhett Allain on May 27, 2010 I don’t know why they call it a tail drop. Here is a video: The link I clicked that brought me to this video said the equivalent of “OMG!” That is not what I thought, really I am not sure what is so impressive (except that he didn’t fall off the skateboard). If the original…
Hey, look kids! There’s Big Ben.
Posted by Rhett Allain on May 20, 2010 And there’s parliament. Ok – sorry, I had to make a “Tom (Swans on Tea)” title for this one. Tom, forgive me. Here are two great circular motion videos. First, this one is from Dale Basler. He made himself a fine little floater-type accelerometer. Better than just make it, he made a video of the…
Preemptive MythBusters: Giant Water Slide Jump
Posted by Rhett Allain on May 16, 2010 I am excited. This Wednesday, the MythBusters are doing the giant water slide jump. Maybe you are new to the internet and you haven’t seen this video. Here it is: And since it is as old as the hills, of course I have already analyzed it – actually twice. First, the video is fake –…
Blue laser awesomeness
Posted by Rhett Allain on May 13, 2010 Yes, green laser pointers are cool. Especially when you use them to make stuff fluoresce. Ok, what about a blue laser pointer? They are getting surprisingly cheap (Amazon has a 10 mW for pretty cheap). Still not cheap enough for me. But, you know what? Some of the physics majors here at Southeastern Louisiana University…
How do color filters work?
Posted by Rhett Allain on May 4, 2010 So you have seen these color filters (or gels as they are also called). When you look through a red filter, everything looks red. What do they do to the light? I am not going to tell you the answer. However, I will show you some examples so that you can figure out the answer…
