As I shared in my earlier post, Glow Stick Bath Time Fun! I read on Knowledge Weighs Nothing that you can ‘recharge’ or ‘pause’ your glow sticks by putting them in the freezer. I had to try this!
After playing with glow sticks earlier this week, I decided to put them in the freezer after we used them for about 45 minutes. It was interesting, the pink glow stick immediately began to dim, as the fluid moved more slowly. The other glow sticks seemed to hold their glow for a really long time. I was sure this was not going to work.
So, I kept on checking on the glow sticks. They seemed to still have a 'glow' to me, so I thought yesterday evening, why not try it? Worst comes to worst, I have to throw out the glow sticks because they are dead. I was so sure this would not work, I even didn't bother to take photos with the good camera. All of these photos or iPhone photos! The photo below is from several hours of sitting in the freezer.
But...they worked! I was totally excited! The glow was fabulous--really comparable to the first time we used them. I wondered how long I would need to defrost the sticks --- not long at all! They seemed to really heat up in the room temperature air and then the warm bath water really quickly.
While I know glow sticks are the not the most expensive items, but hey...ever dollar counts! And...I hate feeling like I am throwing away this huge piece of plastic after only using it for a short bit.
How can I recharge and reuse glow sticks? Here's the plan!
The next time you use your glow sticks, put them in the freezer while they are still glowing. Then, simply remove from your freezer just before you are going to use them. I did not need to 'crack' my glow sticks again. They simply glowed on their own as they thawed.
I put these glow sticks back in the freezer again. I'll periodically update this post to share the status. You can see that the sticks are losing their glow faster than the first time. I wonder, how long can glow sticks last? How many times can I recharge them?
