Chair Challenge Explained! Math Dad vs Science Mom

So on our Math Dad versus Science Mom
series, he has given me a lot of logic puzzles, but today I’m going to give him
a challenge. You ready for this? It’s called the “chair challenge”. So I’m gonna set up our camera right
here and then here’s how it works. I’m going to face the ball with my feet
directly to the wall and then I’m gonna take two steps back. Toe to heel. Toe to heel, and then we’re gonna slide the chair in front of me, and I’m going to
bend over. You need to be pretty close to a 90 degree angle and have your head on
the wall. The top of your head should be on the Wall. Pick up the chair and then
stand up. That’s all there is to it, and as you can see from my demonstration
it’s not very difficult and now I want to see if you can do it. Ok. Doesn’t look too bad. One. Two. Slide the chair in front. Top of your head on the wall. Lift the chair and stand up. Science Mom for the win! What do you think is going
on? You have tiny feet. Yeah, so my feet were putting me further away from the
wall, so I had less leverage. So if you watch Math Dad and me, we have our feet
next to the wall and then I takes two steps back and he takes two steps back.
He’s a few inches farther back and that might not seem like it makes a big
difference but when you have a fulcrum and you’re trying to lift up from your
waist being that much further back makes an enormous difference. So do you think you could pick it up if you were closer? Yeah! All
right let’s try. Math Dad’s answer about the feet is essentially correct this exercise has everything to do with your center of mass,
and it turns out that being just a few inches farther back from the wall makes
all the difference in the world as to whether this is possible or impossible
for you to do. And women, in general, tend to have slightly smaller feet in
proportion to their body height than men so most women are able to do this
exercise where most men cannot simply because their feet size puts them just
far away back from the wall where it becomes an impossible challenge. And then
if you have a more muscular torso and more body weight in your upper body this
also makes this a little bit more difficult and impossible to do.
