Recently, I wrote about how it's possible to explain the lift from an airplane wing without mentioning Bernoulli's principle, which … well … ruffled a few ...

For a 'street science' experiment I approached holidaymakers with a ping-pong ball and a funnel, to show them a classic and counterintuitive science demonstration. It involves something known as ...

Materials Needed: Ping-pong ball, straw and someone to blow hard. The first step in this physical experiment is to hold the straw in your mouth straight up and blow hard to make a good air stream.

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. RUBEN: Good evening and welcome to This Is Your Theorem. Tonight we honour the great Swiss scientist ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

Step 1: Cut the typing paper the length of the sheet. Step 2: Fold one of the sheets (save the other for experiment #2) of paper (without creasing it) from top to bottom. Bring the top edge about 1/2 ...
