This video goes into great depth on two of the most well-known tumblers, what they provide, and what to look for when buying one. @thecoldestwater The Coldest Water vs Hydro Flask – Who’s colder after 48 hours? #experiment #hydroflask #thecoldestwater #48hours #water ♬ original sound – The Coldest Water Here are some of the things you should consider before making a purchase:Insulation –This is probably the most important factor to consider when purchasing an insulated tumbler. You’ll want to make sure that the tumbler can keep your drink cold for an extended period of time. A good way to test this is to put your drink in the tumbler and then leave it for an hour or so. After that time has passed, check the temperature of your drink. If it’s still at the same temperature as when you put it in, then the tumbler is doing its job! Low-quality tumblers aren’t as good at keeping drinks hot or cold because they don’t have as good of an insulating layer.Does not leak –The fact that a tumbler doesn’t leak is the most crucial feature to consider. This guarantees that nothing you put in the tumbler will leak out. Furthermore, no liquid will spill out of your drink onto your desk or table, regardless of whether you accidentally knock the cup over or if it is dropped.Spill-proof –This Coldest Water Bottle features a lid that locks in place so that it cannot be unintentionally removed. These lids are designed to prevent spills when the drink is being transported or if it is accidentally knocked over and are highly practical for travel thanks to this function, whether you’re driving or roaming around town.Tumblers of higher quality cost more, but they last longer than those of lower quality. Additionally, because of their improved insulation, your beverages will keep at the appropriate temperature for a longer amount of time and won’t spill on your hands if they are accidentally dropped.Disclaimer: All content in this video is for informational and entertainment purposes only and does not constitute a certified or licensed experiment.
