You may have seen puking pumpkins before, where a jack-o'-lantern appears to be spewing forth a hot mess of seeds and pumpkin guts.
Those are gross and entertaining, sure, but this Halloween, you can raise your erupting pumpkin game with an Oozing Pumpkin, as explained in an entertaining video from Facebook and YouTube personality Bearded Science Guy.
You'll need some water with food coloring, dish soap, baking soda and white vinegar. By withholding the vinegar until the exact right moment, you can control the reaction until your favorite bunch of trick-or-treaters stops by.
Bearded Science Guy calmly and competently talks through the demonstration in less than a minute and a half, even explaining the science behind how it works. And unlike some Halloween tricks, this looks simple enough even for the Pinterest-challenged among us.
The Facebook video has been watched 78,000 times and shared more than 1,000 times, so don't be surprised if you see a few of pumpkins merrily oozing away as you make your candy-getting rounds.
