Students in art professor Rod Strickland’s first-year sculpture class will show off a 75-metre long Rube Goldberg machine in the SoCA Armouries building tonight — Wednesday, April 4.

The chain-reaction contraption will run down the main stairs to the front hall for a surprise ending, promises student Alice Sacharoff: “Trust me, you don’t want to miss it!”

The public is invited to see the sequence in action starting at 7 p.m.
