Sharky-Locks and the Three Gummi Bears

Need another excuse to buy candy this October?  Like cheap entertainment? Of course you do! How about some do-it-yourself grow-animals? For a buck or two, you can have a hundred edible expanding critters of your very own.

You need a few gummi bears or other gummi snacks (I grant you they are of questionable nutritional value, but they have their uses) and water. That’s pretty much it — see what we mean about cheap? 

I started with three gummi bears and one much larger gummi shark which had a disturbing layer of opaque white gummi on the bottom. 

If you want to know how much your gummi critters grow, you might want to trace around them or measure them, or just set some of your gummy snacks aside for comparison later. I had an electronic balance handy, so I used it, but that’s definitely not necessary:

The growing:  You need a container that can hold your gummi animals with a little room for expansion, and enough water to keep them covered:

And now we wait.  You may notice some expansion an hour after you begin, but your animals will look significantly bigger after 12-24 hours in water.  A few things to note: If you plan to eat your critters once they expand, please refrigerate them during the soaking process (this may slow their expansion somewhat, but you will also slow the growth of not-so-delicious bacteria). Whether you are refrigerating or not, set your critters somewhere and leave them alone as much as possible; if they jostle around too much, they may just dissolve and leave you with an unimpressive pool of colored sugar-water.

After a 20-hour soak, one of the bears intimidates his dry brother:

The “after” measurements:

This bear grew about three times as large as it was originally, and the shark about twice as large (it might have expanded further if given more time but it fell apart after being handled.)

Here’s a brief explanationof growing gummi snacks.

Extensions to try:  Soak your critters in distilled water, salt water, soda or juice, or try soaking an expanded critter in salt water.  Do some brands of bears hold up better or expand more?

(In case you were curious: Yes, you can spell it either way: gummi or gummy.)
