• Hang a 1 Kg mass by a piece of masking tape (just wrap the tape around the hook of the weight).  With the weight dangling, yank upwards on the tape. The tape will break if the yank is quick enough.
• Instead of yanking, hoist weight upwards slowly and tape will not break.
• Tape breaks much more easily than string, and is easier to hold on to.

Location

• Masking tape located in L35, above the sink, on a peg.
• Weight located in L02, section A1.
