  • so today I am going to talk about how you might improve the jump rope and the

  • first question it comes to mind is well what's wrong with a jump rope? And I'm going to

  • tell you two reasons why the jump rope

  • has room for improvement. The first reason is that there is a narrow width at the

  • bottom. As you can see on my feet are there's just not a lot of room between my

  • feet and the rope and this means there's a great chance that the rope might get

  • snagged on my feet if it moves left or right.

  • And the solution to this is really a problem. You see the solution is I'd just have

  • to jump higher.

  • That gives me more room for my feet. But when I jump higher that means I have to work harder.

  • That makes jump roping a little bit less fun.

  • So I wonder if i could change the jump rope's shape.

  • Would there be an easy way to just maybe it may be flattered at the bottom?

  • That would be awesome.

  • Here's one way to do that.

  • One way to change the shape of a jump rope is to simply add weights. So with no weights it

  • looks a lot like a V, but with weights it starts to look like a U or even a

  • box shape.

  • And so I wanted to know

  • how effective is this? How effective is adding just little tiny weights that have

  • a force that changes the shape of a jump rope?

  • So I decided to test it.

  • So here's me jumping in slow motion without weights.

  • What you notice is that it's

  • very much a V shape that comes very close to my feet.

  • And so you can try to memorize what that looks like very quickly.

  • This is with weights, just little tiny weights that are so small you can't even see

  • them but there's some washers there.

  • And you can see me jumping and you notice that it's a fundamentally different

  • shape.

  • These are just ten little washers on each side.

  • and it made a huge

  • difference

  • in the shape of the jump rope. That's pretty awesome.

  • Here they are blown up. So this is before, this is after, and if you look at it

  • you can fundamentally see that

  • the left hand side would be a lot harder to jump rope than the right hand side

  • which is a lot more room for error for example

  • I would encourage you to try this at home.

  • Maybe if you get a super long jope rope that you like to jump rope with

  • a lot of people,

  • may be you can fit even more people by flattening out the bottom. And I don't

  • recommend metal washers, although those were good for testing.

  • Try using something soft maybe beanbags or something else-you can use

  • your creativity

  • And if you want to learn more

  • like what is the actual shape of a jump rope

  • or how was the experiment tested or who originally came up with the idea feel

  • free to check on my report.

  • Happy jump roping.

so today I am going to talk about how you might improve the jump rope and the
