Some everyday objects and utensils hide functions that most are unaware of. The hole in the pasta spatula, for example, can be used both to drain the food and to measure a portion of spaghetti. The wooden spoon placed horizontally on the pot helps prevent the water from rising up and spilling. And the beach cooler… It hides something very useful.

Not all coolers have this advantage, but in many cases the lid can be filled with water, which can then be frozen to keep drinks cold longer. This very useful trick for the summer has gone viral on TikTok and most users have stated that they had never done it.

Several videos on the platform explain in detail what to do. First, we must look for the hole in the lid, which is usually on one of the sides. The next step is to fill this part of the fridge with tap water, cover the hole and put the lid in the freezer (as long as it has enough capacity). In a few hours, the water will have frozen.

Many people have stated that it is a very practical hack, but there are also those who consider that it could be a bad idea to carry it out. Some Internet users say that there must be air in the lid so that the energy transfer is low and it keeps the cold better. Others complain about the weight that the fridge will acquire if we freeze the top.

However, some of the videos that show this method accumulate millions of views, in addition to thousands of likes and responses. So if you didn’t like it, at least you surprised.

For those who are not sold on the idea, you can try other tricks that will also help keep the drinks in the cooler cold. The first consists of adding a lot of ice and salt, which will help the cans and bottles to drop before the temperature. Wrapping drinks with kitchen paper and covering them with ice will achieve the same effect, as will using a compressed air spray (if we have one, of course).
