Probably the World’s Largest Harmonograph

This is just a quick update on our Prototyping the Harmonograph post of a couple of weeks ago. We since installed the PWLH (Probably the World’s Largest Harmonograph) in the gallery, and it has been up and swinging since the start of the Festival of Numbers on 11 March. Why do we call it “probably…

Prototyping the Harmonograph

These days, I rarely go behind the scenes in our workshops here at the Science Centre, but for the upcoming harmonograph installation at our Festival of Numbers I got the opportunity to do just that. A harmonograph is a pendulum-driven drawing machine that combines two or more harmonic movements to produce beautiful patterns of graceful…

A surprising twist

When you work in a science centre, you tend to become quite familiar with all these interesting phenomena one gets to experience in a good hands-on exhibition. So when we make a new discovery, we tend to get all the more excited. That happened to me when I visited the Exploratorium in San Francisco a…

Slowing down time can help

Most science centre professionals will agree that the best way of experiencing a phenomenon is to observe the real thing, or better yet, get hands-on with it. That’s what science centres are all about. A good example is the Science Centre Singapore’s Strobe Fountain exhibit that demonstrates the stroboscopic effect with real water droplets, right…

Can you ride on those square wheels?

About two weeks ago, we posted a video on our “Science It” Facebook page inviting our Facebook friends to identify the object which was posted. Over the weekend, we revealed what the object is, and invited guesses on what the object demonstrates. Have you figured it out? Well, as mentioned in our post over the…

An hour with… the Rubber Pavilion

Individual Science Centre exhibits usually get no more than a few minutes of attention, but spending a whole hour near one can be interesting… Singapore has had rubber trees since 1881, and you can learn all about the history, cultivation, harvesting and processing of this versatile natural resource at the Rubber Centenary Monument in the…

An hour with… the Double Gravity Well

Individual Science Centre exhibits usually get no more than a few minutes of attention, but spending a whole hour near one can be interesting… The Gravity Well is a classic and very popular exhibit, probably found in every science centre. We have a few of them as well, some of them set up as donation…

An hour with… the Earthquake Simulator

Individual Science Centre exhibits usually get no more than a few minutes of attention, but spending a whole hour near one can be interesting… The ‘Shake House’ earthquake simulator is tucked away in the back of the ‘Earth: Our Untamed Planet‘ exhibition. It is a room furnished like a kitchen with a sofa and coffee table….

An hour with… Audio Kinetica – the Ball Machine

Individual Science Centre exhibits usually get no more than a few minutes of attention, but spending a whole hour near one can be interesting… Audio Kinetica is a large glass box, inside of which a number of balls (I counted eighteen) are rolling around on wire tracks, knocking on bells, pushing levers, cascading over xylophones…
