Dear Coca-Cola,
To you, this holiday bottle is probably just a fun novelty item. To teachers, however, this is a cheap (and unbreakable) alternative to a round-bottom flask, suitable for young children.
I like to use these bottles as lenses. Filled with water and held at arm's length, they produce images like this one.
In a darkened room, one can shoot a laser beam through the water-filled bottle and observe the refraction.
Last year, I bought two before they were gone from the shelves at my local WalMart. This year, I got a dozen.
Here's hoping that these will be released again next year.

Thanks, this is a neat idea. My daughter loves gazing balls, snow globes, and the like. I hope my local Walmart has them too!
My daughter is in high school. She took one of these to lunch and reported that she and her friends had a blast goofing around with it.
