Can You Crush a Human Using the Atmosphere?
Air. I bet you never even notice that it’s there. Yet you are swimming in an ocean of it every day. If there’s a literal ton of air pressing down on you all the time, so why don’t we feel it? We look back at the history of physics to...

How to Make a Lemon Battery
Hank shows us another SciShow: Experiment! This time he's tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in the...

Exploring Black Markers with Chromatography
We are using a scientific method called chromatography to see what colours have been used by different manufacturers to make their black markers. Surprisingly black colour hides a bunch of bright colours. To take the experiment a bit...

Outdoor Activity: Anti-Gravity Water
Alex knows that every time we do an experiment the result should be different from what he normally expects to happen. This time he said that water would not spill if we turn the cup upside down. So I asked him to do just that and water...

Upside Down Glass of Water Trick
Defying the laws of gravity? Try turning a glass of water upside down without spilling. Place a card over the top of the glass filled with water. Quickly turn the glass upside down, holding the card in place and then, carefully let it...

Science Experiment: Magnetic Corn Flakes
A quick experiment with magnetic cornflakes for a breakfast. If you read the label on the pack of corn flakes, you will see a list of vitamins and IRON. Magnet attracts that small amount of iron.

Science Experiment: Putting Lit Candles Out with Glass
This is a simple science experiment but so much learning is happening here. We confirmed that oxygen is needed for fire to burn and compared how different volume glasses influence the speed with which candles go off.

Science Experiment: Saltwater Egg
We are back home and we are going back to experiments. A raw egg sinks in water, but can we increase water's density to make it float? Alex adds salt to see what would happen. Then I carefully add fresh water on top of salted one (not to...

Noisy Coin in a Balloon Experiment
It is just fun to spin a coin in a balloon. But we used a 7-sided 20p coin that made some interesting noise.

How to Pop Balloons with an Orange Peel
This is how to pop a balloon…with an orange peel. When I squeeze orange peeling, you can see that it is spraying something around. That liquid is called limonene and it easily breaks latex of the balloon causing it to pop.

How to Make Colours Appear from Words
How cool is this activity with magically appearing colours from words! You would need regular markers, a permanent black marker, paper towel and water.

Science Experiment: Clouds in a Bottle
Do you know how clouds form in the sky? Here is a quick experiment I showed to Alex to demonstrate how pressure change can do just that. To do this experiment at home you would need: a plastic bottle, rubbing alcohol, air pump, champagne...

How to Make a Chemical Traffic Light
How fun is this chemical traffic light experiment!? Liquid changes colour from green to red and later to yellow. The best part is it is repeatable. Just shake the bottle to start again. For this experiment you would need: - Dye called...

How to Make a Pythagoras Cup
This experiment shows how Pythagoras Cup works. A long time ago Pythagoras made this cup (also known as a Greedy Cup), that empties itself if too much drink is poured.

How to Make a Glass Object Disappear
Don't trust your eyes! If you cannot see it, it doesn't mean that it is not there. When you place a Pyrex stir rod in the vegetable oil, it disappears. The secret here is that vegetable oil has nearly the same index of refraction as...

Science Experiment: Funnels
This is fun funnel experiment that proves that an empty bottle isn't, in fact, empty and to fill it with water we need to make sure that air can escape. If a funnel is properly sealed to a bottle and a lot of water is poured into it at...

Science Experiment: Color Mixing
We do different types of activities with boys, but mixing is Max's most favourite thing. Here Max is mixing Yellow and Blue colours with a help of baking soda and vinegar reaction.

Science Experiment: Candle and Water
This is an impressive but simple experiment for children. We did it with Alex about two years ago, so it was Max's turn now. But this time I added a bit of a twist though. I spread food colouring on the bottom of tea candle, lighted it...
