In the last episode of MythBusters, they wanted to see if a tornado could make some glass cut off a person’s head. The first attempt was just to take some glass and through it at a simulated human neck. Clearly, this wasn’t quite the same as a tornado. So, here was their plan. If they…

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 –…

A small duct tape mistake

Yes, I am going to talk about the MythBusters latest duct tape episode. A couple of pre-post points: They call it “duct” tape. I call it duck tape. It doesn’t work very well with ducts. Also, it is good for water proofing stuff – you know like a duck. For the rest of this post,…

It is good to be wrong

I have one more comment about the previous MythBusters episode where they compared two cars crashing into each other at 50 mph vs. one car crashing into a wall at 100 mph. At the end of the episode, Jamie reflected on the experiment. He said something like (regarding how he incorrectly thought one car at…

I already mentioned the MythBusters’ crashing two cars episode where they correctly doubled the speed of a pendulum type object. Overall, this was a very visual (although expensive) demo. There was one part that left a sour taste in my mouth – the final explanation from the narrator. First, they showed this. And then they…

In the last episode of MythBusters, Adam and Jamie wanted to test something that Jamie had said earlier: “Two cars crashing head on at 50 mph is the same as one car crashing into a wall at 100 mph” Jamie was wrong, but that is not what I am going to talk about. Instead, I…

So, I complained about MythBuster’s explanation of relative velocity. How would I explain this? I would start by saying that velocity is relative. Here is the definition for velocity: I put the “avg” in there because it is more true. If the acceleration is zero, I could drop this. For the rest of this post,…

MythBusters and physics terms

In the last episode of MythBusters, they tried to reproduce the following experiment. Suppose you are driving in a car at 60 mph and you shoot a ball backwards at 60 mph (with respect to the car). Will the ball just drop (with respect to the ground)? Actually, it is a cool demo – I…

In a MythBusters episode some time ago, Adam and Jamie jumped off a building. There was some cool stuff in this, but I want to focus on the acceleration data they collected. Before jumping into a pit of foam, they first wanted to test the set up by dropping a dummy into it and measuring…

On a previous episode of The MythBusters, Adam and Jamie made a lead balloon float. I was impressed. Anyway, I decided to give a more detailed explanation on how this happens. Using the thickness of foil they had, what is the smallest balloon that would float? If the one they created were filled all the…
