Make chicken sounds with a cup

Make chicken sounds with a cup Long, long ago, instead of mice and monkeys, Reeko used chickens for all of his experiments (Reeko switched to lab rats and monkeys when one of his chicken experiments went terribly wrong). Chickens proved to be perfect for scientific exploration! They didn’t each much, they were easy to find, and when you were done with them, well, we all know that chicken soup is good for your health (unless, of course, you are the chicken). In fact, the only difficult thing Reeko found when using chickens for science experiments was catching them but even that Reeko solved with science. In this experiment, we’ll use a cup, a piece of string, and a paperclip to make a chicken caller. Oh,…

Make a homemade hearing aid – collect sound vibrations using a paper cone

Make a homemade hearing aid Everything that moves makes a sound by causing vibrations or movement of air.  If you don't believe this, next time Dad is kicked back in his easy chair watching TV, sneak up behind him with two metal pots and bang them together real hard.  Now listen carefully to the whooshing sound as Dad flies out of his chair and runs towards the door.  By the way, if Dad offers no reaction and instead lies incredibly still, throw some water on The vibration or movement of air is the basis for sound.  Our ears collect these air movements and change them to nerve signals that are sent to our brain.  Our brain interprets these signals as sound. So what if we…

Make a homemade Kazoo musical instrument

Homemade Kazoo 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 Reeko 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 to. In this experiment, we’ll create a musical instrument called a Kazoo. With it, we’ll make beautiful music… or noise, depending upon your musical preference. 1 – Cut a small square of wax paper, about 1 inch larger than the end of your cardboard tube. 2 – Center the wax paper square over the end of the tube and wrap the edges. 3 – Put the rubber band around…

Have you lost your marbles?

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 or vibration of an object. The sounds we hear every day are formed by the vibration or movement of air.   Basically what happens is sound makes tiny particles in the air, called molecules, bump into each other.  The molecules bump into each other compressing and then expanding to cause the wave to move like a falling column of dominos.  This vibration of molecules is passed…

Good, good, good vibrations – sound and vibrations experiment

Good, good, good vibrations 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 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 he moves it - yes?  Let Reeko Cut off a piece of two foot string (2'). Using a rubber band, attach a metal spoon to the midpoint of the string. Wrap the ends of the string around your fingers. Rest your fingers in your ears (don't stick 'em in too far or you'll poke your brains out!). Standing next to a table, rock your body back and forth…
