After walking through the Missouri Botanical Garden to see the lights during last year's Christmas season, we thought we might be able to recreate the floating color balls which they have in their fountain near the Climatron.
Our campus fountain is a rectangle, not as big as MoBot's, but large enough to make a statement. We ordered the glowing balls from two different places, all are solar so that they charge during the day and begin glowing at night. Just like MoBot's ours will cycle through various colors.
I got one delivered on Saturday morning and left it in the sun all day and when it got dark it began to turn color, changing from yellow to pink to red to blue to green and back again. Here's what it looked like.
It looks like a pink moon in the sky although it was just sitting on the sidewalk in the dark. They all are meant to float in water or just sit on a patio table or even a bar if that's what floats your boat. Our fountain pond is in the sun all day long so they should really charge up well.
