When it’s hot outside, you always want to make sure to stay hydrated. Keeping a beverage with you at all times is almost a necessity to make sure you don’t have to deal with dehydration. However, drinking lukewarm water or a sports drink when the temperature is scorching is far from refreshing. If you don’t have time to let it sit in the fridge for an hour or two, the quick solution is to put ice in it, but most ice cubes never fit into a bottle of water or Gatorade.

Thankfully, there is a solution out there, and it’s quite inexpensive to boot! They’re called the Progressive International Ice Stick Flexible Trays, and it will give you thinner ice cubes so that it can fit into the mouths of most water bottles. This set has two trays, each of which make eight ice sticks, and will cost you a little over $8.
