With this experiment we’ll cause marshmallows to make funny faces and demonstrate a scien-terrific principle called pressure.

As science enthusiasts ourselves, we understand the importance of staying up-to-date with the latest developments in science. That’s why we bring you the latest discoveries, innovations, and advancements in the world of science, keeping you informed and up-to-date on the latest trends and breakthroughs.
Magical inflating balloons experiment – an experiment to demonstrate thermal expansion and contraction via heating and cooling
One of the basic physics principles is that heat causes things to expand (get bigger) and cold causes things to contract (get smaller). Things such as air will contract and take up less room when cooled. Similarly, things will expand when they get hot.
Magical expanding soap – the funny microwave and soap experiment inspired by Jacques Charles.
Ivory soap differs from most other brands in that it floats in the water. The reason – there is air whipped into the soap which makes it lighter than water. The small air pockets in the soap make for a very interesting effect when the soap bar is heated up.
Look Ma’ – no hands – air pressure science experiment
The pushing force of air is called air pressure. The closer you are to Earth, the greater the air pressure. The farther away from Earth (in other words the higher your altitude), the less the air pressure. And remember, pressure is coming from all around us. Here’s an experiment to demonstrate the pressure of air…
How capillary action makes water go up – capillary action science experiment
Even though we usually think of water as running downhill, it can indeed flow upwards using a process called capillary action. This is the very scientific principle that explains how water goes from the soil upwards into the stem of plants.
Make a homemade barometer science experiment – how to make a real working barometer from a soda bottle.
The air pressure around us affects our weather. Notice how your weatherman always mentions various pressure systems (low-pressure system, high-pressure system, etc.) and how they will affect tomorrow’s weather. In this experiment, we will create a tool that lets you gauge the pressure of the air around you.
Extracting life from a plant science experiment – demonstrating how a plant’s leaf and stem act like a straw
Plants are living creatures. They need food and water just like people. But how do plants get food?
Homemade clouds in a bottle science experiment – water vapor and its behavior related to temperature, expansion, and contraction.
The clouds in the sky form when water vapor is cooled enough to form tiny water droplets. When moist, cool air rises to a higher altitude, it cools, water droplets are formed, and voila – you have clouds. In this experiment we’ll duplicate this same process by causing the air in a bottle to rapidly…
Can we please lower the pressure in here? Bernoulli Principle science experiment.
Named after Daniel Bernoulli, the Bernoulli Principle states that as the velocity of a fluid increases, a decrease in pressure occurs. The mathematician Daniel discovered many new ideas regarding fluids and pressure. For instance, Bernoulli, who had earlier begun to study medicine, wanted to know about the relationship between the rate of blood flow and…
Build a real working hovercraft! A science experiment to demonstrate the principles of pressure and lift.
So you want your very own hovercraft. Well once again, Geek Slop is here to help. Of course, it’s only big enough to hold a mouse (maybe two if the first one scrunches down real low) but hey, you’re not old enough for a driver’s license anyway…
