How to make ice melt quickly: scientific methods and popular experiments revealed
In hot summer or in emergency situations, melting ice quickly becomes a need for many people. This article combines hot topics and scientific experimental data from the Internet in the past 10 days to reveal effective ways to accelerate ice melting.
1. Physical methods to accelerate ice melting
| method | principle | Effect comparison (time for complete melting of 500g ice) |
|---|---|---|
| Let stand at room temperature | natural heat exchange | About 120 minutes |
| metal container conduction | Metal has high thermal conductivity | 45-60 minutes |
| Stir ice water | Increase the temperature difference between contact surfaces | 25-30 minutes |
| hot water shower | direct heat transfer | 5-8 minutes |
| Salt aid | lower freezing point | 15-20 minutes (with stirring) |
Recent TikTok popular challenges show, useCopper pot + coarse salt + stirThe combination method can melt standard ice cubes in 3 minutes and 40 seconds. The video of this method has been played more than 8 million times.
2. Comparison of efficiency of chemical methods
| chemicals | concentration | Increased melting speed | security |
|---|---|---|---|
| sodium chloride | 20% | 200% | food grade |
| calcium chloride | 15% | 350% | Need protection |
| ethanol | 50% | 180% | Flammable |
| Urea | 30% | 250% | irritating |
Note: The latest experiment from the YouTube science channel "Veritasium" shows thatCalcium chloride solutionThe best ice melting effect, but may corrode metal containers.
3. Engineering-grade rapid ice melting technology
Recent hot events show that airport de-icing operations adopt newBiodegradable ice melting agent, its features include:
Tesla patent documents revealedLaser de-icing systemSparking heated discussion, the system achieves selective heating by precisely controlling the laser wavelength (980nm), and laboratory data shows that it can remove 5cm thick ice within 20 seconds.
4. Practical skills for family scenes
| scene | Recommended plan | Things to note |
|---|---|---|
| Cool drinks quickly | Salt water + wet towel wrap | Salt concentration does not exceed 10% |
| Refrigerator defrost | Hot water basin + fan convection | Early power outage |
| Outdoor first aid | Aluminum foil wrapping + body temperature conduction | Avoid frostbite on skin |
#LifeHack, a trending topic on Twitter, suggests: Putting ice cubes into a sealed bag and rolling them with a rolling pin can shorten the melting time by up to 70%. This method is especially suitable for bartenders to make ice quickly.
5. Abnormal phenomenon warning
Reddit user reports indicate that the following methods may backfire:
The latest research in the scientific journal "Nature" points out that ultrasonic waves at a specific frequency (40-60kHz) can accelerate the destruction of ice crystal structures, but household equipment cannot yet achieve laboratory results.
Conclusion:Choose the appropriate method according to your needs, daily recommendationsSalt + metal conductionCombination plan, hot water pouring can be considered in emergencies. Regardless of the approach, safety and environmental friendliness should be prioritized.
