Capacitance. It's not an everyday word but that is what touch lamps use to make and break mechanical connections. According to website, 'capacitance is the capacity an object has to hold electrons' and every touch lamp has a certain capacitance. 'This means if a circuit tried to charge the lamp with electrons, it would take a certain number to 'fill it'. When you touch the lamp, your body adds to its capacity. It takes more electrons to fill you and the lamp, and the circuit detects that difference.' With little plug-in boxes, any lamp can apparently be turned into one that is touch-sensitive, although Florian Schulz's new Son touch lamp (left) may stave off readers' DIY impulses.

The stylish floor lamp, with adjustable head, is available for $16,370 at Magazzini Showroom, 9/F, Horizon Plaza, 2 Lee Wing Street, Ap Lei Chau, tel: 2814 1663.
