Hey YouTube, Jim here! Welcome to Top10Archive! How do you pass the time during those rainy
days stuck at home? Your video game collection proves no thrills and you’ve watched more
TV than you’d care to admit – so what’s next? How about these ten at-home science experiments
to pass the time?! They’re safe, easy to pull off, and would be approved by any parent…
for the most part. Before we get started (and perhaps before you blow up the kitchen doing
one of these experiments) go ahead and give us a like, subscribe to the channel, and click

10. Color-Changing Milk When milk’s staple color of off-white does
nothing for you, perform this experiment for a tie-dye effect! Simply pour milk into a
dinner plate, to where it’s about ¼” deep. Then, add red, yellow, green, and blue
food coloring to the milk, placing the drops close together. Take a clean cotton swab and
simply dab the center of the milk, but don’t stir! Now, add a drop of liquid dish soap
to the same end of the swab and place it in the milk, holding it there for 15 seconds.
What you should get is a burst of color, like a milky firework. The reaction stems from
the soap’s ability to break up and collect non-polar fat molecules, leading to a colorful
display as the fat molecules are collected by the soap molecules.
9. Slime Time! Here’s an experiment to gross out your parents
with, and all it takes is a ¼ cup of water, ¼ cup of Elmer’s glue, ¼ cup of liquid
starch, food coloring, and a mixing bowl and spoon. To create your own gooey slime, mix
the glue and water in the bowl. Once completely combined, add 6 drops of your choice of food
color. Consider green, just to give it that perfect slime hue. When the color is ideal,
stir in the liquid starch. What should be in your bowl is a blob of colorful goo that
you should be able to pick up and stretch. Creating the slimy texture is a series of
polymer strands found in the glue and starch which link together to form a durable, stretchy
substance. 8. The Foamy Fountain
Now we’re moving into “parental guidance” territory, so be sure to have an adult or
nearly adult around and protective eyewear for this experiment! What you’ll need to
create your own fountain of foam is a 16-ounce plastic bottle, ½ cup of 20-volume hydrogen
peroxide, 1 tablespoon of dry yeast, 3 tablespoons of warm water, liquid dish soap, food coloring
of your choice, and a small cup. What you’ll be doing is creating a foam from an Exothermic
Reaction, or one that creates heat! To start, add hydrogen peroxide to the soda bottle followed
by 8 drops of your desired food coloring. Then, add 1 tablespoon of the dish soap and
mix it by gently shaking the bottle. In your small cup, add the warm water and yeast and
mix for 30 seconds. When you combine the yeast mixture into the soda bottle, prepare for
a fun, easy-to-clean up mess! 7. Diet Coke and Mentos
Chances are you’ve seen this reaction before, but it’s a classic we can’t pass up! Gather
a bottle of Diet Coke, a package of Mentos, and, if you want to avoid a mess, a tube.
Simply open the coke and, all at once, place half of the Mentos package into the Coke.
You’ll need a tube or funnel so they’re added at the same time. Almost instantly,
you’ll be met with a geyser of Diet Coke, caused by what many believe to be a reaction
between the carbon dioxide in the Coke and the dimples on the Mentos candy. When the
candy is added to the Coke, it speeds up the release of carbon dioxide gas and the dimples
allow a mass amount of bubbles to form, leading to the eruption.
6. Traveling Water This experiment demonstrates cohesion, and
all you'll need to do it is a length of string, some water, two glasses, and tape. Also, this
experiment can be messy... so we suggest taking it outside. Cut the string to roughly 2 feet
in length, and fill one of your two glasses to the halfway point. Soak the string for
10 seconds in the water, and using your fingers, wring out the excess water. Now hold one end
of the string above the empty glass, and the other end into the glass with water, using
your index finger to keep the string along the bottom of the rim as you pour. Start slowly
and pour faster, and watch the liquid transfer glasses.
5. Make Your Own Lava Lamp These popular lamps from the 60’s have started
to make a comeback, but nobody says you have to spend upwards of $50 to enjoy one. In fact,
all you need is a bottle, vegetable oil, water, food coloring, and Alka-Seltzer! First, take
your bottle and fill it almost to the top with vegetable oil and fill the rest with
water. You’ll notice the water sinking to the bottom. Add some food coloring of your
choice, which will sink to the bottom and mix with the water. To get that lava flow
moving, simply break the alka-seltzer into small pieces and add them one at a time. Due
to differences in the polarity and density of water and oil, the two won’t mix; and
though real lava lamps don’t use oil and Alka-Seltzer, the science behind them is essentially
the same. 4. Egg Into A Bottle
Remember this trick? Some of you may have done or seen something just like it in school.
Start by getting yourself a wide-mouth glass bottle. Next, rub a little bit of vegetable
oil around the mouth of the bottle. You'll want to hard boil your eggs, and then peel
them. Once peeled, take some paper and using a lighter, ignite one end of it and drop it
into the bottle, flame side down - quickly placing the peeled egg on the top of the bottle
and watch as it gets pulled in, staying intact. Can't get the egg back out of the bottle?
Well, try blowing into the neck while holding the bottle upside down.
3. Real Life Water Bending Probably the cheapest activity on our list,
all you need is a nylon comb and access to a water faucet to prove the power of static
electricity. Turn the water faucet on until it is in a small, steady stream. Once done,
run the comb through your hair several times - about 15-20 times should do it. Now slowly
move the teeth of your comb towards the stream of water, roughly 3 to 4 inches (8-10cm) below
the faucet itself. As you move the comb closer to the stream you'll notice the stream bends
more and more. This is a great experiment to do and you’ll finally have your hair
combed! 2. Make A Paperclip Float On Water
To do this, all you need is a wide bowl filled with water, and 2 paper clips. Start by bending
the paperclip into an L-shape, and carefully place the unfolded paper-clip across the smaller
side of the L-shaped clip. Now slowly, and carefully lower the paper-clip into the water.
You will notice that the unfolded clip will begin to float. This is due to surface tension,
and it's more of a suspension than true floating... either way though, this is pretty awesome
to us. Oh yeah, another thing you can do is put a dab of dish soap on your finger and
touch the surface of the water and watch all floating objects sink.
1. Water and Fire Take one candle, a plate, some water, a narrow
glass, and matches and you have yourself the makings of a quick, easy, and fun science
experiment! Place the candle in a plate filled with water, light the candle, and immediately
cover it with the glass. As the fire burns, it will increase the pressure in the glass,
which will push against the water; but once that flame extinguishes, the pressure lets
up, allowing water to flow into the glass. Voila! Science! Thanks for watching! Now go
and experiment! Oh, but before you go, if you learned something from this video, please
