Something I haven't heard of so far(don't hold me to that, I skimmed through), is having the members split up into groups and complete a challenge with abstract materials.

For example, we hold something called a "box challenge". The challenge works like this:
The students break into groups of 5-6, and each group is given identical amounts and types of materials. The groups are then instructed to build something to complete a challenge (tallest tower, bridge that can hold weight).
This gets the adrenaline pumping and allows the students to remember their first meeting better.
However, we do not use our first meeting to find new recruits, we use it to hook them in; we use school orientations to find new members and tell them about this meeting and others.
