Well, it was 27* when I went out at 7:30am on Thursday morning to see if you really need the uber bitter cold temps to make bubbles freeze or if below freezing temps are all that are required. I blew some directly on the tree, some popped, some stuck and froze. I blew a few more up to the sky and down toward my leaf-covered grass, again a few popped a few stuck and froze. This is one bubble that landed on the leaf-covered grass and froze. One perfect bubble for one last day. It’s supposed to warm up and rain for the weekend so this first frozen bubble experiment concludes here.
