We were given a sheet of restrictions and stuff about our Visual Arts body of work. I'm just copying this from the sheet we got:
Dangerous materials must not be used. Any HSC Body of Work submission that may be considered dangerous to health or safety may not be marked or returned to schools if marked in corporate marking.
Works considered dangerous could include those with faulty electrical wiring and/or those which incorporate very sharp points or cutting edges such as glass, mirror fragments, barbed wire, rusty corrugated iron and/or broken machinery. Hypodermic syringes, needles, bodily secretions and blood products must not be included in any artworks.
If you wanted to make the sculpture you could probably do that, take photos of it and submit it as Documented Forms instead.
