How to build the trigger for a trebuchet?

I am building a trebuchet as a school project. It is made of popsicle sticks and the arm is 40cm long. The counterweight weighs about 500-600 gms. I need some ideas on how to make a good trigger mechanism.

I have though about using a pin....but that is not reliable. The only materials I can use are string, popsicle sticks and wood glue. But, I am also open to other ideas using other materials.

I need to get this done in the next 12 hours....so, I would really appreciate quick replies. Thank you! If you need more info, include what you would like to know in your replies.
