When you throw a paper airplane on Earth the wings create a lift that pulls it up, but gravity pulls it down; this mix makes it glide forward and down. In microgravity, the wings still create lift, but with nothing to pull the nose down, the lift force causes... show more

The science of levitation: The figure-eight shape of the paper creates joined wings. When it spins there are equal forces of lift and drag on each side, both moving in different directions The board creates a base for airflow to be maintained close enough to the paper

One of those plays that we've seen several times this season in KC. It's drawn up for Juju with two vertical stems from Watson and Hopkins on third down. The play is there to be made, but Mahomes pulls it down.

Airplane wings aren't some rigid chunks of metal: in fact, they probably have a bit more flex than you'd expect. This is the behavior of a Boeing 747's wing in a turbulence. It can move 6m up and down safely.

The video is a hoax. Notice the airplane is stabilized but the contrail is not. This is what happens if you start with an authentic video of plane and digitally remove it, but you do not do a careful job of stabilizing the original before dubbing in the fake plane and orbs.

This game will test your limits, knock you down, lift you up and throw you back again. But those who love it rise stronger every time. Thanks to the amazing Bengaluru crowd for the love, support and cheers. We will be back stronger. 🏏 #RP17

This guy used a car jack to lift an entire sidewalk and injected polyurethane underneath to stabilize and level it. This type of job can cost all the way up to $25 a square foot. But….. hear me out here, what if we just kept the jack in the ground and buried the $50-$100 jack right where it’s at? Wouldn’t that save a ton of money? Could it work? Would it work?

Damn. Takes him feet to back twice with the same throw. Kinda like a headlock but instead of clubbing the head he bites it, pulls it left to off-balance, then runs him down & rotates him to his back

Bernoulli’s Equation: P + ½ρv² + ρgh = constant Mind-bending science that looks like pure sorcery! A lightweight paper loop floats and dances in a high-velocity air stream, seemingly defying gravity. Fast-moving air over and around the loop creates a low-pressure zone above and along its curved surfaces. Higher atmospheric pressure underneath pushes it upward, trapping it in the airstream. The Coanda Effect makes the air hug the curve of the loop, keeping the airflow attached and giving it remarkable stability. Gravity pulls down, while the pressure difference lifts up — creating a beautiful dynamic equilibrium. With nothing but moving air molecules, you can guide the loop wherever you want. Invisible forces at work!

Eagles come out the sky in many different ways but this when they hold their wings outstretched the slow their speed is by far my favorite. It showcases the amazing power in their wings and their ability to control themselves mid flight.

Everyone says slow down when you see a deer and if you hit it, it won’t be that bad. Depending on the size of the deer, you can still easily total your car, so once again if you can swerve out the way, that would be the best way to minimize it. This car looks totaled.

Asked Bears offensive coordinator Declan Doyle if there was an opportunity for a mailbox type of throw to Rome Odunze: "It was, so we called a movement really. Rome ends up popping cause there is a safety down there in the corner and he hit it with speed. You know, Caleb breaks contain and he feels like he's got green grass to go get a first down. You know, I love the play cause, you know, we end up converting there, but if he saw it, obviously he would love to take the big play right there over the top before he works back."

You’re not doing enough Plyos and Medballs. Just like Speed work, you need to attack Plyos and Medballs from a variety of angles and intensity. Pair it up with the theme of the day for speed and lift and you’ve got the layout for your best summer ever.

Call on the field was a 1st down. After replay assist, they made it 3rd and 1. But watching the replay looks like James Cook got the 1st down Replay assist seems to be very inconsistent this game when it steps in and when it doesn’t

I don’t know who needs to hear this but if life is dragging you down… Light a fire and cook with it Learn to bake bread Start a garden and tend to it The power of food is undeniable. It allows us to create, provides variation, and spreads joy to those you share it with. Love you guys.
