The bee and the flower. Bees fly from flower to flower gathering nectar, which they make into food, benefiting the bees. When they land in a flower, the bees get some pollen on their hairy bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating* the plant. This benefits the plants. In this mutualistic relationship, the bees get to eat, and the flowering plants get to reproduce.

Learn to Curl!Curling involves two teams of four ktniag turns sliding granite stones across ice to circular targets known as the “house.” The object is to get as many stones as possible closer to the center of the house than the other team. A Learn to Curl session starts with 30 minutes of classroom instruction followed by 2 full hours on the ice learning curling techniques, and finally, playing a game.Curling equipment is provided. Plan to wear warm, comfortable clothing such as sweatpants and sweatshirts. Hats and gloves are also recommended.WHEN: November 12 5:30pm to 8pm December 10 5:30pm to 8pmWHERE: Lutheran Health Sports Center, 3869 Ice Way Drive, Fort WayneCOST: $25 (non-members)/$20 (members)CONTACT: or 260-438-0689

You were testing the balls wrong. punting distance is important, but what is more important is the hang time (how long it stays in the air) to allow your team to get down and prevent a return. I would like you to revisit this myth and test which ball stays in the air longer.

A lighter football should have higher initial speed from the same kick but in your experiment the initial speeds were identical.

I agree with anthony on this one I just saw this episode and was expecting hang time to be tested yet distance was the only thing tested, if distance was the case u could try filling it with a heavier gas and attempt to test newtons law

Whoops, I realised I forgot to multiply by Pi. That would make the mass of the cylinder of air about 8649 tonnes. So it’s true then! :)
