In this experiment, we’ll construct a sound collector that will allow us to hear a whisper from across the room.
Make a homemade hearing aid – collect sound vibrations using a paper cone experiment.

Our articles provide a glimpse into the past, helping readers understand how the world has evolved over time. We also cover topics such as archaeology, US History, and historical preservation, allowing readers to learn about the different ways that history is studied and preserved.
Make a homemade Kazoo musical instrument – a science experiment to create vibrations of compressed air (sound)
Ah, the sound of beautiful music. But what some will call music, others will call noise. The lab rats and monkeys are partial to Metallica while Geek Slop is more of a Beethoven aficionado. Put the two groups of musical tastes together and well, you have a big fight over what radio station to listen…
Have you lost your marbles?
Sound surrounds us all the time. You may awaken in the morning to the sound of an alarm clock or Dad snoring. During the day you may hear the cacophony of auto traffic or the hustle and bustle of city life. But all sounds have one thing in common. They are formed by the movement…
Good, good, good vibrations – sound and vibrations experiment
Sound is actually nothing more than moving air and the way we perceive that moving air with our ears. Now you may be saying “Wait a minute Geek Slop… sound is made by moving air?”. Sure. Think about it. Your dad moves a lot of air – right? And he makes a nasty sound when…
Sucking an egg into a bottle – heat and pressure experiment
Here’s an interesting experiment. We promise you’ll be talking about this one at school the next day. Find a bottle with a long, narrow neck and set it on the table. The opening should be just small enough to keep the egg from falling inside.
Skating on thin ice pressure experiment – a pressure science experiment for kids.
Pressure – you feel it at school, your teacher feels it during class (yes, a room full of little scientists can be stressful for some teachers), and your dad feels pressure when Mom asks him for the tenth time to take out the trash. Here’s an interesting experiment that demonstrates a different kind of pressure…
Plastic cups in love experiment – a demonstration of Bernoulli’s principle
What does a flying airplane and a pitcher’s curve ball have in common? Well, besides the fact that both travel through the air at amazingly fast speeds – both are based on a principle called Bernoulli’s principle. Bernoulli, (pronounced Burr New Lee) was a Swiss mathematician who liked to piddle around with these types of…
Marshmallows making funny faces science experiment – demonstrate the principle of pressure.
With this experiment we’ll cause marshmallows to make funny faces and demonstrate a scien-terrific principle called pressure.
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.
