Learn how to build an Iron Man arc reactor

Billed as a "build, craft and design experience", the Makers' Block festival is the largest-ever event for "makers" (artists, builders, crafters, designers and engineers) by "makers" in Singapore.

It is held at Suntec City Mall, Tower 5 at Level 2, daily from 10am to 8pm, until Monday.

Admission is free.

Different craft classes will be held every day, so participants can learn to create blueprints, build terraniums and even an Iron Man Arc reactor.

Each class is open to all ages, with a fee of $20 per hour.
