When Skyline Luge Sentosa opened 10 years ago yesterday, just 191 customers took the "gravity thrill ride" down towards the island's beaches.

Since then, it has been anything but an uphill struggle for the company, with about 4,000 visitors riding its toboggans each day. The annual number of riders has risen by 120 per cent in the decade, with average annual revenue growth of about 20 per cent. It had a record 1.5 million riders in the last financial year.

The company's new general manager, Mr Ryan Williams, attributes the growth to the attraction's ability to appeal to all age groups. Last year, $4 million was spent on adding ticket and photo counters, plus LED lights to one of its trails. "The site is now more appealing," he said.

Skyline Luge Sentosa celebrated its 10th anniversary yesterday by announcing a programme to teach students science concepts such as force and velocity. Mr Williams said: "We want to show that science and physics can be brought into the real world."
