Hydroflask 40oz and The Coldest 40oz | 24-Hour Temperature Test

In this video, we experimented with two 40 oz water bottles. One is the Coldest and the other is the Hydroflask bottle.

Hydroflask is better? I actually have no idea.

Let’s do the 24-hour temperature test. Both are 40 ounces in size and filled both of evenly as possible with ice and then water.

24 hours later, we remove the lids of both the bottle and inserted the thermometers, and this is what we found out.

After 24 hours, the Hydroflask was 48 degrees and the coldest was 45 degrees 3-degree difference in coldness.
