You ll build a roller coaster track for marbles using foam pipe insulation and masking tape and see how much of an initial drop is required to get the marble to loop the loop.
Marbles going through pipes sound.
Of course despite the scientific explanations that don t really sound scientific enough.
Air can get trapped in the network of pipes as water passes through them and the force can cause the pipes to jostle and disperse the air pocket creating a sound like marbles rolling.
Abstract this is a really fun project even if you don t like going on roller coasters yourself.
They say the sound comes from water trickling through pvc pipes which gets distorted through concrete before emerging as the sound of falling marbles.
Can you find a correlation.
It all started when the straits times forum published a letter by bank executive joseph wong who kept hearing the sound of falling marbles in his flat.
Plumbing is a good.
The sounds are primarily coming from the pipes in most cases.
However this usually produces a single sound.
Water bubbles in sanitary pipes.
A sudden change in water flow mixed with soapy bubbles will create air pockets that burst and echo through the pipes.
This causes a vibration in the pipes and creates the sound of marbles dropping.
This change in pressure rattles the pipes and creates clanging sounds which will sound like marbles dropping as the sounds pass through concrete walls.
But this makes pinpointing the origin even more challenging.
Then again think about this.
This phenomenon has been in the news lately.
If the sound alters as it moves through a building it means actual marbles and pins can t be the root cause.
The sound it creates is similar to that of marbles dropping.
Building experts told us that it s due to the pipes mosquito traps or vibrations that go through the walls.
