Dark Matter is an episode of BrainPop and can be found in Science, aired on January 11, 2006.
Tim and Moby are having a staring contest until the power goes out; they receive a letter, asking them about dark matter. Tim explains that dark matter is mythical, and no one has discovered it. He also explains that no one knows what is behind it. Moby suggests that it is caused by "flying invisible turtles" or spaghetti, much to Tim's annoyance.
When the power goes out, Tim trips but pulls himself back up. Look closely at the vocabulary word "dark matter" at the corner, and you can see Tim using it as a grip.
