We tried some ice balloons during Winterpocolypse, but didn’t get them outside until the last two days, which even with a low of 16 and a high of 25 was not enough to completely freeze the water in the balloons. We should have started them at the beginning of the invasion of the northern weather, but we didn’t have consistent water, and needed to conserve for vital things like drinking. Making ice globes is probably easier in places who know how to do winter.
