From the same guy who created the viral video of Diet Coke and Mentos causing a fun little explosion in 2005, causing people everywhere to do the same, Denver TV personality, author, and science teacher Steve Spangler has a new trick you can try out:  "The Self-Carving Pumpkin Trick."

That's actually putting it lightly... and not entirely true... but fun, nonetheless.  First off, you do carve the jack' yourself.  Then, you push the face in, and there's a chemical reaction inside it that makes the face "come back out," or more like explode all over the place.
