[SilentOne46]

They forgot about those other two melons..

[DeanMalenko]

@mileyroxforev same raction as with mentos, the carbon dioxide in the 7up suddenly found a place to "sit on" when the ice cube was dropped in because even though it looks smooth, ice cubes have little bumps and impurities on them so the carbon dioxide in the 7up gathers there, bubbles form and eventually get so big that because they are lighter than the 7up want to float to the top. so they leave the ice cube making room for another bubble to form, and if that happens really fast.. you know :)

[MeepullStewray]

You're very very nice lol

[leodemi23]

what liquid did he pour in the watermelon?

[mrkingb144567890]

@leodemi23 is not a liquid when you collect oxygen and hydrogen into a same baloon or cup u can pore it into a pepsi bottle by creating a whole under the bottle to let the gasses into the bottle and fire it it will explode

[kiashadowwave]

@leodemi23 It's methanol or something of the sort, an alcohol you can buy it at any automotive store (gas line anti-freeze) or at a hobby shop (RC car fuel). Basically alcohols at room temperature evaporate into a gas, and at a certain ratio of fuel-to-air it becomes very, very flammable. Using a lighter (in the back) he ignited them.

If you "wait" longer, it will saturate the air more and produce a stronger explosion, but if you wait too long it will become over-saturated and not do anything.

[genthe1994]

"You're fine, you've got insurance." LOL, loved it!

[OldSchoolSkill]

With Halloween approaching, some people might attempt to recreate these effects with pumpkins. It's a good idea to follow Steve's advice: use caution and only try this with the help of an educated professional like your science teacher.

Have fun and BE SAFE.
