In this science experiment we will mix molecules to make a glitter globe (i.e. a “snow globe”). We will combine rubbing alcohol, vegetable oil, and a few other tiny, shiny things to make a cool science toy.
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.
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.
Pascal’s law has many practical applications, including hydraulic lifts, brakes, and jacks. It is also used in many industrial and manufacturing processes, such as in the production of plastics, metals, and chemicals. Here we will demonstrate Pascal’s law with a pen cap and plastic bottle.
Heating an object sealed inside another object can produce some exciting results. Heat causes things to expand (or get larger). Cold causes things to contract (or get smaller). Let’s demonstrate with this experiment.
Most substances have three states – solid, liquid, and gas. When they go from a solid to a gas, they usually turn into a liquid in between. Ice is a good example. It first melts into a liquid and then evaporates into a gas. Sublimation is when a chemical compound turns from a solid to…
Liquid nitrogen, represented by the equation LN2, is often used in higher level science experiments. In this experiment, we’ll create a liquid with the same “ultra cold” properties found in liquid nitrogen. You’ll need two plastic bottles, one slightly smaller than the other.
In this experiment we will build a real working volcano. After mixing just the right amount of ingredients together, we’ll add the final item to make our volcano ‘blow its top’ spewing red lava down the sides. Yes, this is the famous “Baking Soda Volcano” experiment – found exclusively at Geek Slop (and on the…
So, you don’t want to be a kid and instead want to be an elephant because you’ve been told elephants never have to brush their teeth? Well, we have news for you – there’s a lot more differences between kids and elephants than just their teeth.
