I don't hear marbles. I hear the sound of concrete thumping on concrete in the wee hours of the morning from the roof top as I live on the highest floor. Normally happens past midnight to 2-3am. Never happens in the day. Questioned the security guard but supposedly no one is up there at that hour as there is no access (door to the roof is locked). Seen a few neighbours come and go, but I kind of got used to it.

Aiya, not ghost lah, where got so many ghost so eng play marble in the middle of the night and at so many various places.

Should be due to some structural contraction or water in the middle of the night. Used to hear it in my parent's old place but after moving to new flat, no more. So most likely happened on old flats.

MYSTERY OF FALLING MARBLES

Strange sounds due to water in PVC pipes

Paranormal investigators' society comes up with explanation for sound of falling marbles with an experiment

By By Goh Wen Zhong

IF YOU'RE still hearing the sound of falling marbles in your flat, it could be your neighbour washing up at the sink.

After a five-hour experiment on Wednesday, members of the Singapore Paranormal Investigators (SPI), a society made up of paranormal enthusiasts, have come up with what it thinks is the real reason.

They say the sound comes from water trickling through PVC pipes, which gets distorted through concrete before emerging as the sound of falling marbles.

This phenomenon has been in the news lately.

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. A flurry of letters from other people followed, all saying they had also heard the sounds, and wanting to know the cause.

Some even suggested there might be a supernatural explanation.

But in a Sunday Times report on June 12, building experts said it might be caused by the rattling of water pipes when there's a change in water pressure, the contraction of high-strength steel cables embedded in pre-fabricated floors, or children actually playing with marbles.

The SPI was not satisfied. It wanted to narrow down the possible causes.

Said the society's treasurer, Mr Eugene Toh, 26, an insurance agent: 'We want to allay the concerns of the public with conclusive and reliable evidence to point out the cause.'

The society's month-long investigations hit paydirt on Wednesday when four of its members gathered at Mr Toh's home, an HDB maisonette in Bedok.

On the upper floor of the two-storey house, they dropped marbles big and small, flushed toilets, turned on taps and recorded the sounds.

They also recorded the sounds from the floor below.

They then compared the sound frequencies with a recording they had made of falling marbles.

Bingo.

SPI president Kenny Fong, 36, an assistant professor at the University of Macau, said: 'The frequency signatures of sound flowing from the sink through water pipes and that of falling marbles were almost identical.'

Asked about SPI's findings, Mr Shek Kam Chew, 68, who has 39 years of experience as a structural engineer, agreed that it was plausible.

For the SPI, which was registered as a society last month, the investigations do not end here. Mr Fong and his team want to do more tests to bolster their claim.
