Life can be challenging at times. Everyday tasks can become problematic, such as removing wrinkles from clothes or cleaning your favorite shoes without causing damage. Fortunately, engineering and science-based life hacks are available to help. Four of our favorites are listed below.

1. Toothbrush With Salt Makes Everything Better!

A typical day begins with a brushing of the teeth. However, adding a pinch of salt to the toothpaste makes everything better. You should do it while the glue is being applied to the brush.

Brush your teeth in a circular motion. The extra salt can help you get rid of the yellowish surface of your teeth. Salt will brighten your smile by making them whiter than they've ever been.

Furthermore, according to Lifehack, salt contains chlorine, which kills all microorganisms. It will keep your teeth in good shape and extend your life. 

2. Micellar Water To Clean Shoes!

Although micellar water is excellent for removing makeup, it may also be better at eliminating stains from shoes without causing harm. It makes sense considering that this washing water must be robust enough to remove waterproof makeup but gentle enough for the skin. Take a look at the life hack offered by a Twitter user below.

3. Remove Gum From Hair or Shoes With Ice Cube or WD-40! 

Have you ever had gum trapped in your shoe or hair? Thoughtful Co. shared a couple of chemical life hacks that might help you get out of this jam. Using an ice cube to freeze the gum makes it brittle, making it less sticky and simpler to remove.

Spray the sticky stuff with WD-40 if it's gum trapped on your shoe. The lubricant will make the adhesive less sticky, allowing you to remove it easily.

While you probably shouldn't spray WD-40 in your hair, if you have gum caught in it, apply peanut butter on the afflicted area to loosen the gum, comb it out, then wash it off.

4. Make Your Beer Cool Faster!

Nobody loves a warm beer, and the internet is full of suggestions for keeping your brewskies icy cold for maximum enjoyment. There are two main techniques that WhatCulture shared - one that uses chemistry and the other that uses thermodynamics.

Method #1 includes putting a lot of salt in a bucket with ice and water, then plunging your beers to chill down. Because the dissolved salt in the water lowers the freezing point of the water, it chills your drinks quickly. Whereas it would typically freeze solid at 0°C, the water temperature might drop to -20°C, speeding up the chilling process.

Method #2 is ideal for chilling small quantities since it eliminates the need for a large filthy pail of water. To use this approach, wrap a moist piece of kitchen roll around the bottle or can and place it in the freezer. Since liquids are often stronger heat conductors than gases, it cools significantly faster. Liquids have a larger density of molecules, and energy (i.e. heat) can be transported considerably more efficiently because the molecules "bounce" off each other more often.

Keep an eye on your quickly cooling brews since water expands as it freezes, potentially turning your tasty beer into an explosive device.
