Blowing bubbles is a great stress reliever as it requires a deep breath before making a bubble and it elicits giggles which are sure to relieve stress.
Check out this video my daughter and I took when it was 19' F.
I dare you to try this at home! I would recommend two things - use small bubbles like wedding bubbles (these were huge and took a while to cool), and catch the bubble on the wand like we did so your bubble doesn't pop before freezing.
Tell me how it worked.
