Not every thing
Great video, but there are some parts that make sense.
1. When he dips the match and that lights it, for all we know, it might have pure patasium an the end of it, which lights on contact with water.
2. The weight floating in the water says "16 tons," but that doesn't mean that it really is that heavy. It could be hallow.
3. The part about the aliens and the alternet universe. That happens to me all the time
