While few of the scientific offerings formally follow the scientific method or test an explicitly stated hypothesis, even those videos veering more towards demonstrating various principles, theories, and laws still offer visitors a chance to learn something about how the world around them operates. By this point, it should go without saying that many of the following videos contain procedures that may be dangerous to perform at home or without the proper equipment and/or training. Please do not duplicate any of these experiments unless assured that they are entirely safe for amateurs.
