Clubs Day is an event at Lisgar Collegiate Institute which happens at lunch, usually on the last Wednesday of every September. During this occasion, the many clubs of Lisgar, including Spacesim, set up a table in the gym and advertise their club. Spacesim often brings along the Planetarium and Liquid Nitrogen Marshmallows. Clubs Day occurs halfway through the Week of Hype.
The purpose of Clubs Day is to advertise one's club to potential members, particularly to grade nines. It generally occurs during lunch, and anyone throughout the school can walk through the gymnasium and sign up for any clubs that interest them. As such, Spacesim attempts the most memorable display they can muster.
