Crystal Suncatcher

This neat science project will require a few days of patience, but has a beautiful ice crystal reward at the end, perfect for winter!

To start, poke a hole through the rim of a clear plastic container (we used the top of a Pringles canister) with a needle or push pin. Make slightly wider with a pen or pencil, then set aside.

In a microwave safe bowl heat 1/2 cup water for about 45 seconds, or until warm. Add 1/2 cup Epsom salts, stirring until dissolved. Travis loved making this “potion”.

Fill the container lid with the salt solution and set someplace that gets a lot of sunlight. Now wait! Here’s how our crystals looked after 24 hours:

And now after 48 hours!

The science here is fairly simple. When you stir the Epsom salt into the hot water, it doesn’t disappear of course; it dissolves. But when the water evaporates off, the Epsom salts are revealed again. Hence the beautiful crystals!

To capture your experiment into a work of art, cut the rim off an identically sized lid (again we used a Pringles container). Hot glue them together carefully so as not to crush the crystals.

Thread a length of string or yarn through the hole you poked in the beginning. I worried we might crush the crystals because our hole was quite tiny, so we hot glued on our string instead, which works in a pinch! Now it looks like Jack Frost has come to call at our window.
