This is why I bought a clipboard with a pen holder and always carry a tape measure. If you do both of these things, you will never be questioned and can get into the White House bedrooms while the president and first lady are necking.

You read that right: I'm happy to announce that we're doing MythBusters: The Reddit Special! Yup, we're handing over the editorial of an episode to YOU. So if you've got a TESTABLE myth you want us to tackle, post it below. If you've got a myth you think we messed up and should do again, then put it here in this thread. We are also interested in novel methodologies if you guy have something interesting in that regard too! If you want us to blow something up, here's where you can tell us! Or if you've just got a burning desire to send something weird and wonderful to its doom courtesy of the rocket sled, then you know what to do. (Post it below!)

Basically, we'll tackle the myths you guys have suggested with one obvious caveat - the myths have to be PG-13! We’re definitely up for some fun with stuff like farting, but anything more R-rated than that (and we know how Reddit works) is not going to fly! In two weeks' time, the MythBusters R&D team will trawl through this entire thread and select the myths / stunts / questions / requests that are the best fit for the show, and then we’ll fast-track the episode to a screen near you in early 2016. Happy posting!

The Small Print: As always, there's small print that a pair of (admittedly nice) lawyers are insisting I put in and it's this: By submitting to MythBusters any information (such as your story idea) you understand that you are giving MythBusters (Beyond Productions and its related entities, licensees and assigns) the right to use the information in all media for any purpose whatsoever and you will not be entitled to notice of use or compensation of any kind if the idea is used. So, there it is.

been rewatching mythbusters a ton lately, so i did a little photo study while watching the trapped on an island with only duct tape episode today!! hope you enjoy.

Randomly, in a Pacific Grove Bar. His favorite one was the cement truck! Super nice guy.

A few years ago, for my final project in my low-speed aerodynamics class, I had to perform an aerodynamic study of something as long as I utilized my university's low-speed wind tunnel.

Once the assignment was given, everyone (being devoted aerospace engineers) decided to do studies on F-117s, F-16s, and other aircraft to replicate previous studies performed.

But no not me, I was that one oddball who decided to take a completely different approach to the project. For some reason, at the time, I couldn't help but think of that famous quote from The Incredibles: "No capes!". Despite the fact that this specific example was talking about the hazards of wearing capes, I eventually realized that society is pretty convinced that capes offer no advantages in flight, but no data was present. I myself, was also very convinced that capes offer no advantages, but hey, let's put that myth to the test!

For my experiment, I wanted to measure the forces acting upon a "Superman" in flight at speeds of Mach 0.2 - 0.7, using Reynolds numbers (a value that can be used to scale models to their full scale counterparts in flight) that are similar to that of a jet fighter aircraft's performance. I found that these speeds are fairly close to what Superman would do assuming he's not breaking the sound barrier.

I bought a 12" Iron Man figurine that would be my "Superman". Due to the streamlined profile of his armor, I could approximate that Iron Man is a bare human body.

Then, I attached a strain gauge to a piece of PVC pipe and epoxied the PVC pipe to Iron Man's groin. That way I could place my figurine in a Superman flying pose and position his body to experience the airflow like that in flight.

As the airflow swept across the figurine, the drag forces would deflect the PVC pipe, and the strain gauge would be "strained". Using some engineering mathematical magic, I could translate the voltage reading from my strain gauge to total drag force experienced.

The premise of this experiment is to levy off of Newton's 2nd law of motion, in that F=ma (F=d/dt(mv)) or the sum of the forces acted upon an object equate to the object's mass times acceleration. This basically means that more drag force (what I'm measuring) means less flight velocity (physical inference).

Now the control of my experiment was obviously testing the figurine with no cape. However, my variables were scaled capes of varying lengths and materials. For this experiment, I chose to use muslin fabric (a common/lightweight fabric typically used to test patterns before making actual clothing) and nylon fabric (a common heavyweight material used in actual costume design for capes and superhero suits). Each of these materials would have three different size variants: short (up to the figurine's knees), medium (up to the figurine's feet), and long (past the figurine's feet [roughly 14" inches in length]).

My hypothesis was that the larger and heavier the cape, the more drag forces would be experienced and therefore, a slowed flight velocity.

So after a long day of performing these tests, with tons of data to process, the following data charts were produced...

At first, I thought something was wrong with my test setup, however after conferring with my professor and other university faculty, to my own amazement, the heavy and bigger the cape is, the less drag force is experienced. Basically, you fly faster with capes!

However, there was a big stipulation attached. The larger and heavier the cape, the more its gonna flap around, creating instability. But nonetheless, the average of those fluctuations still deems lower drag forces then without a cape.

So why is this? This sounds completely counter-intuitive. With a little aerodynamics, we can easily justify these results...

When you are in flight, there are two primary forces in play that drive the motion of an aircraft: Thrust and Drag (Lift and Weight are also contributing factors, but for this study, they are not important to consider).

If we assume our thrust to be constant, only drag will affect how fast our figurine will travel. There are several different types of drag forces that all sum up to give us the total drag force. The two most dominant types of drag forces are skin friction drag and profile drag.

Air is considered a fluid, in that it can displace indefinitely with shear forces (imagine flowing water). Additionally, air is made up of content (roughly 20% oxygen, 70% nitrogen, and 10% other stuff). If we flew through the air, the air would "brush up" against our bodies and impart friction (like car tires having friction on the ground). The more surface area (and surface roughness) we have that is parallel with the flow of air, the more frictional drag we would experience. With capes, our surface area would increase, and therefore our frictional drag would increase. This is a fairly trivial observation that governed a lot of intuition leading to the initial hypothesis.

Now the other dominant drag force is that of profile drag. Profile drag is the drag that is experienced due to how "blunt" an object is with respect to the airflow. Imagine you are driving down a highway in your car: you open up your window and hold your hand out. If you held your hand in a way such that the edges of your hand is laid flat (parallel to the ground) you would feel some push back from the airflow. Now if you turned your hand so that your palm was facing the incoming airflow, all of a sudden that push back would be far more significant. That is intuitively what profile drag is.

The way that aerodynamicists can evaluate profile drag is by looking at the region of disconnected air flow behind the object of interest. The larger that area of "disconnected" flow, the larger the profile drag.

When you have a blunt object with a sudden change in geometry, the air has to move around that object and reconnect. But if your object is suddenly really blunt, the air can't reconnect quick enough, resulting in the area of disconnected flow. This phenomenon is why aircraft are designed with streamlined profiles, so that the air can move around the object and reconnect behind the object.

Without a cape, the shoulder's of the figurine act as a blunt object, and the airflow separates at the figurine's shoulders, resulting in a large separation area and therefore a large profile drag.

The cape acts like a streamlined surface that helps to delay the separation of the airflow to further downstream of the figurine, resulting in a smaller separation area and therefore a lower profile drag. The longer the cape, the further downstream the separation. The heavier the cape, the better surface for maintaining flow over the surface to delay flow separation.

Now when comparing the magnitudes of profile drag and friction drag, profile drag is significantly more powerful as a drag force than friction drag. So although capes increase your friction drag, they also reduce your profile drag. That reduction in profile drag significantly outweighs the friction drag, resulting in a lower total drag and thanks to Newton's 2nd law, we can infer that capes as a matter of fact do make you fly faster. However, I don't recommend trying that: you will find that controlling your flight would be far more difficult.

With that I call the myth that capes inhibit your flight busted!

I also aced that final project! Lesson learned: any class can be fun, you just gotta find an intriguing way to approach intriguing questions.

Next generation enjoying the show!

While trying to figure out couples costumes for tonight’s party I realized we were limited by my husband’s mustache that looks like Jamie’s. Because I’m extra when deciding who I wanted to be, Kari would have been the obvious choice for most wives. I’m not most wives.

I never thought I would have ever met Adam Savage!! He is one of the coolest guys i could have ever expected to meet!!
