Our polymers are more than just awesome, great fun, beautiful, and educational, you know. Our polymers are awesome, great fun, beautiful, educational, and long-lasting.
How long-lasting are they, you ask? I really don’t know yet. The polymers in this Christmas decoration are seven years old and still going strong.
What you see up there is a Christmas candy jar with about a tablespoon of Spangler Science’s Clear Jelly Marbles, about three drops of green food coloring, and a cup of plain tap water. Don’t put the lid on the jar until the jelly marbles and water reach the top of the jar. THEN put the lid on. Once you put the lid on the jar, the marbles won’t grow any more because they need a little air to help them grow. (Please notice that this jar has a lid that seals! That’s important.)
It took these Jelly Marbles only a few hours to grow to the size I wanted them. If I removed the jar’s lid and drained off the water, the polymer Jelly Marbles would shrink back down to the size of rock salt again, but they wouldn’t be “dead;” when I added water again, they would grow again.
Would they still be green? Nope. Not if I rinsed off the food coloring. I could keep them their own clear, invisible-in-the-water selves, or I could drop in some red, or blue, or green again, or create my own colors by combining primary colors. I could drop in an Easter egg color tablet. I could use a Spangler Science True Color Tablet.
The point is, seven years ago I made a pretty and decorative Christmas decoration using some simple polymers – clear jelly marbles – some food coloring, and some water, and I’m still using that pretty and decorative Christmas decoration this Christmas.
