- Whoo, science rules! - Now we're gonna pour
out the hydrogen peroxide and pour it inside of here. Whoo, look at this, this is insane. - Growing up, I always loved shows like Bill Nye the Science
Guy and Beakman's World because they made science fun, accessible and easy to do at home. And if you're anything like me, you love science experiments,
so why do we talk about something you can
do at home right now? These are 10 amazing science
experiments you can do at home. Number one isoobleck, oobleck is the name for a strange, mucky
substance you can easily make with one part water and
two parts corn starch. As the corn starch is
slowly mixed into the water, it will become tougher the
more you try to stir it up. Once the two are fully mixed together, you'll get a white, slimy goo
called oobleck, or magic mud. Oobleck is different
because it's classified as a non-Newtonian fluid because
it displays properties of both a liquid and a solid. Smack it or roll it
into a ball in your hand to see it harden under physical force. But if you let it rest, it will quickly ooze out of your grasp. The name oobleck is taken from a book called Bartholomew and
the Oobleck by Dr. Seuss, which tells of a sticky goo
substance called oobleck that falls from the sky. If you wanted to get
creative with your oobleck, you can always add food
coloring to the mixture while you're stirring it, just be careful because it can really easily
slip out of your hands. But it's a lot of fun. Number two is the canned rainbow. There are actually two methods of creating a canned rainbow, and neither
of them involves running around on a rainy day trying
to catch one with a jar, you big piece of crazy. Both methods are achieved
by stacking liquids with different densities
on top of each other. The most effective way is to
use a bottom layer of honey, colored dish soap on top
of that, a layer of water, then olive oil and finally add a top layer of isopropyl alcohol. Alternatively, if you
don't have those things, use a few cups of sugar,
water and food coloring. For this method you'll be
adding various levels of sugar to each cup and dissolving each
amount in water with colors. Make sure the water with the
most sugar is poured in first since it will be the heaviest
and will sit at the bottom. From there you slowly add in
your different rainbow layers, going from the mixes with the most sugar to the mixes with the least. Once you're done you'll have a glass of liquid rainbow art to show off. Number three is a miniature electromagnet. It's time to harness the power
of electromagnetism at home. What you'll need first
is an iron bolt or nail, which will act as your
magnet, some copper wire and any kind of battery
that you have in your house. Size double A or D is best. First, you need to wrap your copper wire around your bolt a bunch of times, leaving the other end
of each wire long enough to connect to the battery. Try to wrap the wire as tightly
close together as you can, and if you have enough,
wrap another layer over top to make a stronger magnet. Once the iron object is all wrapped up, you'll need to connect
one end of the copper wire to the positive charged
part of the battery and the other end to the negative. After the connections have been made, you'll have your very own electromagnet to pick up small metal objects. The electricity from
the battery will travel through the copper wire
and into the nail or bolt, giving it a magnetic charge. Number four is magnetic slime,
to create magnetic slime you'll need a tablespoon of Borax powder or some laundry detergent
that contains Borax mixed with about two and
a half cups of water. Empty out the contents of a small bottle of white school glue and
slowly stir in the Borax water. Stirring and mixing this
enough will create the goo, which is pretty fun to
play with on its own. Now, add a bunch of iron fillings
and work that slime around until it's uniform with small iron specks. Once you have a suitable
amount of iron incorporated into your goo substance, grab your magnets and watch as the slime
literally crawls towards them. The magnetic slime is most
fun with powerful magnets, so try to have some on hand before performing your experiment. Also, keep in mind that your
slime will only stay good until the iron fillings go rusty, so don't plan on storing
it for a later date. That could get nasty,
bran all over your hands. Ain't nobody got time for that. Number five is the plant maze. Plants aren't exactly active
or exciting organisms, but they do make pretty good navigators when it comes to finding sunlight. To see them in action for yourself, you'll need a small box
with a lid, like a shoebox, a few pieces of cardboard, scissors, tape, and a little bean plant in soil. Open the box and fashion two small walls out of your cardboard to tape in place. Position them sticking out on either side, creating a little zig zag
maze for your weed bean sprout to figure out, and then
secure them with tape. Cut a decent sized hole
about three inches wide at the top of your shoebox maze. This is where the
sunlight will pour through and guide your plant to victory. Once the maze is ready, water your sprout and place it at the bottom of the box. Then place the lid over
top and tape it shut to make sure no other light can get in. If you leave your little bean
plant and come back to it about four or five days later, you'll find that it is grown
upwards through the maze. Mother Nature's a mad scientist. Number six is a pressurized balloon. For this truly odd experiment,
you'll be inflating a balloon by sucking air out of a plastic bottle. First, you'll need an
empty plastic bottle, preferably something large enough to allow the balloon to expand,
like a large sports drink. Once you have that, cut a
small hole about halfway down the side of it that you'll
use to suck the air out. Next, get your balloon,
lower it into the bottle, and stretch the opening
over the mouth of it. Now that you have the
opened balloon dangling in the bottle, it's time to
start sucking the air out through that hole that
you cut in the side. As you suck the air out you'll notice that the balloon will start to inflate, even though the end of it is wide open. What you are doing here
is creating an imbalance in air pressure by decreasing
the pressure in the bottle compared to the air pressure
surrounding the outside. This forces the balloon
to grow as it tries to equalize the pressure
between the two environments. It's kind of some reverse
mad scientist stuff. It's fun, try it. Number seven is the pasta rocket. This experiment turns pasta
into a miniature jet thruster. The easiest way to do this is
to have a small canning jar, some hydrogen peroxide, dry yeast, and a piece of hollow pasta
that can stand on its end. Pasta like ziti or bucatini
work best for this. You'll need to drill a
small hold in the top of the canning lid that you can place the uncooked pasta over. Once you have everything in order, fill 75% of the jar up
with hydrogen peroxide, then mix in a quarter
teaspoon of dry yeast. As they begin to react and bubble, place the canning lid on the jar without the screw on top,
then stand your pasta noodle over the hole to create
a funnel for the oxygen that is now being released. Now, light the top of
the noodle with a lighter and watch as the steady
rocket-like flame is created. The peroxide and yeast
acts as an oxygen generator while the pasta become the fuel source, creating the same basic
concept for modern day rockets. Number eight is the Leidenfrost Effect. The Leidenfrost Effect
is a scientific reaction that occurs when water meets a surface with a temperature much
higher than its boiling point. First, you'll need a
saucepan or another type of metal container that you
can heat on a stove top. Heat the pan to 374 degrees Fahrenheit and then get a small cup of water. Now, normally when you
add droplets of water to a hot surface, they
go flat and evaporate into a steam pretty
fast, but at 374 degrees, they roll around as
little balls of liquid. Watching the water roll around
kind of seems reminiscent of watching someone run
barefoot on a hot driveway after it's been in the sun too long. Scientifically speaking,
this effect is achieved when the water droplet first makes contact with the surface and the heat is enough to instantly vaporize the
part of the underside. It's amazing because the
vapor created forms a shield under the droplet, which
allows it to roll around without making contact directly
with the heated surface. Number nine are naked eggs. Oh, everybody loves some eggies. For this one you'll need a regular egg from an egg carton, a
cup and some vinegar. Fill the cup up with vinegar
until the egg is covered and then leave it for at least 24 hours. While you're waiting,
the vinegar is dissolving the calcium carbonate that
makes up part of the egg shell, and after a day you can
start to rub the shell away, leaving just the contents of the egg. It's actually amazing,
it's all held together just by a thin membrane,
and the membrane itself is semi-impermeable, meaning
liquid can be absorbed through it, so your new naked egg might be a bit bigger than it was before as it now contains nasty, nasty vinegar. Without its shell, the egg actually becomes rubbery and bouncy, but bounce it too hard
and you can break it. You can also shrink your naked
egg down to just its yolk through osmosis by soaking
it for a day in corn syrup, which has a very low water content. But whatever you do,
don't eat your naked egg when you're done with it,
unless you like your eggs saturated with that nasty vinegar. And number 10 is instant ice. Okay, this one is really cool. In order to instantly create
ice, you'll need to put an unopened bottle of
purified water in the freezer for two and a half to three hours. Once the wait is over you should carefully retrieve your super cold water bottle, making sure not to drop or shake it. Now, once you have your
instant ice making water, you can choose how you want
to trigger the reaction. You can actually watch
the entire bottle of water turn into solid ice in
seconds just by hitting it or slamming the bottle on a surface. You can also pour the
water slowly on a piece of existing ice and create
cool ice formations. Or dip a piece of ice into the water and watch everything
freeze outwards from it. Now, this trick will only
work with purified water since it doesn't contain any tiny minerals or organic material. Since these are mostly
absent in purified water, it can take on temperatures below freezing without becoming solid. If you guys end up trying
any of these, record it and tweet it to me, I
