The summer heat is approaching and unfortunately most outdoor activities are very limited, unless you want to fry!However, most of us don’t want to spend our free time inside the house, the car or in air-conditioned malls, but would prefer to spend time chilling on the beach.
Scenario: You receive a sudden call in the morning: “We’re meeting at the beach in 30 minutes, mate!” While checking the supplies you find out, that there are no cold Pipers* in the fridge. Oh no! Knowing that Piper is not yet in retail stores, you need to get them chilled very quickly. How do you get the Piper drinks cold in only a few minutes?
No problem!There are plenty of options to chill your drinks quickly.For the sake of experimentation, let’s have five cans of Piper at a temperature of 27°C which you want to quickly cool down to 8°C. Put one can in the fridge, one in the freezer, one in a bucket of ice, one in a bucket of iced water and as a special cocktail one can in a bucket with water, ice and salt.
After 10 minutes check the results:
- Fridge (Temp.: 13°C) Temp. of the Piper Drink after
15min: 24.0°C
- Freezer (Temp.: -9°C) Temp. of the Piper Drink after
15min: 4.3°C
- Bucket with ICE only (Temp.: 0°C) Temp. of the
Piper Drink after 15min: 4.0°C
- Bucket with ICE + Water (Temp.: 2°C) Temp. of the
Piper Drink after 15min: 4.6°C
- Bucket with ICE + Water + Salt (Temp.: 0,8°C)
Temp. of the Piper Drink after 15min: 3.7°C
For the fastest method, use the special cooling cocktail of a bucket of water with ice and salt. To optimise your results, you can turn the can from time to time to maintain a uniform temperature inside the can and the bucket. The reason this is such a successful cooling method is that liquids are better at transferring temperature than air. The colder the surroundings and the bigger the contact surface the faster the cooling effect. Ice cubes might be colder than the saltwater mixture but the contact surface is less – the ice cubes don’t cover the can completely. The trick with the salt is that a water/salt solution freezes at a temperature lower than -1°C which results in a liquid with a lower temperature than a normal ice/water mix. Therefore it has a better cooling effect.
