  • Chemistry life hacks.

  • McGuyver Meets Mendeleev

  • in these everyday, chemistry inspired tricks

  • to make your life a little easier, with all

  • the evidence you need to back it up.

  • Now let's get started.

  • Quick Cold One

  • Doggone it, company’s going to be here

  • in 30 minutes and the brews

  • are sitting still in the garage.

  • You want to be a good host,

  • so here’s a quick tip to get those beers

  • down to blissful frosty goodness

  • in no time at all.

  • Take a bucket and fill it with water.

  • Then, add a whole bunch of salt.

  • Go ahead, just twist the lid off

  • the salt-shaker and dump it all in there.

  • Then, when the salt is dissolved in the water,

  • add a whole lot of ice.

  • Swish it around, stick your beers in there

  • and theyll be chilled in under 20 minutes.

  • When salt molecules are dissolved in water,

  • they have the ability to significantly

  • reduce its freezing point.

  • Normally, when water freezes at 0°C, its

  • molecules begin to crystalize and form ice.

  • Salt molecules interrupt this development,

  • which means the water will cool lower

  • than its normal freezing point.

  • With beer cans fully submerged,

  • the entire surface area is covered

  • by freezing cold water, which means it

  • will cool faster than just being on ice.

  • Gnat a Problem

  • Fruit flies have been buzzing around the kitchen

  • and youve come to realize that there are

  • few and far things in this life as annoying.

  • It’s time to make a change and move on

  • to a fruit fly free existence.

  • Here’s what you do.

  • Take a small dish and pour a little bit

  • of apple cider vinegar in it.

  • Then, add a couple drops of dish soap.

  • Put the dish near the fruit fly fiasco,

  • and wrap the top tightly with saran wrap.

  • The final step is to poke several holes

  • in the saran wrap lid, to keep the flies

  • from flying out when they enter.

  • Those little guys are very much

  • attracted to the scent of vinegar.

  • This is because their larvae feed on

  • bacteria that grow in fermenting environments.

  • Then that addition of dish soap breaks

  • the surface tension of the vinegar.

  • So in other words, when a fly steps into

  • the trap and checks out the vinegar,

  • it falls right in, rather than being propped up

  • by the surface tension of the vinegar.

  • Holy Burgers

  • You want to be the grill master of year,

  • but you can’t seem to get your burgers right.

  • Either theyre too pink in the middle,

  • or youve gone overboard and burnt them to a crisp.

  • Good news for you, weve got a technique

  • for the prefect burger, without any health risks.

  • When you squish your patties together,

  • poke a quarter-sized hole right in the middle.

  • When you grill this style of patty,

  • it will cook evenly throughout.

  • Every tiny bit of ground beef in that patty may

  • have potentially been exposed to germ and bacteria.

  • So when cooked, you got to get everything

  • up to a safe 160 degrees fahrenheit.

  • As your grilling your burgers the browning

  • patties are going through a tasty chemical

  • transformation known as a maillard reactions.

  • When food is heated a reaction occurs between

  • sugars and amino acids that gives cooked food

  • its color and its excellent flavor.

  • So by poking those holes in the patties,

  • you open up the center of the burger

  • for more equally spread heat, which means

  • that theyll cook faster inside,

  • without the unnecessary charring outside.

  • And the best part, is the hole will

  • close up when it’s fully cooked.

  • Stink Sponge Syndrome

  • There’s no doubt about it,

  • youve gotta keep those dishes clean,

  • but half the time you wonder to yourself

  • what’s the point when your kitchen sink

  • smells like mildew all the time.

  • That sponge of yours reeks, and

  • it’s time to do something about it!

  • Here’s a quick fix. Double up your sponges.

  • Use one for the first half of the day,

  • and the other for the second half.

  • After every time you use a sponge,

  • it’s important to thoroughly rinse

  • it with water and let it dry before future use.

  • With two sponges, you can always be certain

  • to start with a dry sponge.

  • You see, when your sponge stinks, it’s due

  • to certain odorous chemicals that are produced

  • by bacteria that thrive in wet environments.

  • If you do your best to keep the sponge dry,

  • chances are high that you won’t suffer

  • from Stinky Sponge Syndrome any longer.

  • Big shout out to Jim Hasak for the

  • Stinky Sponge Syndrome lifehack.

  • If you have any other chemistry life hacks

  • of your own, post them down there in

  • the comments and well try to work them

  • into future Chemistry Life Hacks videos.

  • Thanks for watching folks!

  • Well see you again soon.
