I've been watching Big Think a lot lately. Not exclusive to science, though there is plenty of that. It watches a lot like short TED videos. Usually 2-5 mins (sometimes longer, Stephen Fry has an hour+ vid on there) of something philosophical, scientific, or inspiring, etc, and usually present some interesting points. There's a lot of Michio Kaku, Bill Nye, and Neil deGrasse Tyson, which is always good.
I went to the Cincy Zoo last summer and while most of the exhibits were "meh" the cheetah show was jaw dropping. They weren't even running full bore but it was shocking to see in person them cover the ground at maybe 3/4 speed.
Here's a video of her record run - note the ears. The keepers say you can tell when they're really trying to run fast because they pin their ears for max aerodynamics.
Ball pits are just toilets filled with brightly colored balls instead of water.

Recreation of John Wesley Powell (as in Powell Lake)'s speech to the National Geographic Society 125 years ago. Memories of his 1869 (and 1871) trips down the Colorado River (unexplored) through the Grand Canyon.
