Science Tricks

This tennis ball was set alight after it was soaked in ethanol. The trays contain water and washing-up liquid. Methane was bubbled through them to create a row of flammable bubbles. The result is an impressive wall of fire inside a science classroom! Credit: YouTube/David Hill

Burning Tennis Ball Creates Indoor Wall of Fire

Time lapse footage has the extraordinary ability to make the mundane beautiful. In this video by Ian Parks, some magnetic putty moves as if it has a mind of its own, reaching out to stationery magnetic bricks and swallowing them whole. Credit: YouTube/Ian Parks

Magnetic Putty Time Lapse Is Strangely Beautiful

This video was made by three physics teachers in an effort to show ‘the explosiveness of hydrogen, chain reactions and Newton’s 3rd Law’. It’s safe to say, the experiment was a success! The 192-can pyramid is violently decimated by the ‘rockets’, two-litre Pepsi bottles filled with rocket fuel. While it looks fun, it did take six hours to film. Credit: YouTube/David Hill

Smashing a Pepsi Pyramid Using Hydrogen Rockets

This science teacher at a high school in Edinburgh wanted to show his students a chain reaction, and had an unorthodox plan to do so. First, he built an intricate pyramid out of matches. Next, he set them on fire. The resulting video shows that both he and the students were impressed by the results. Credit: YouTube/David Hill
