Here is the way I see it.
He has said yes to performing at an event, he is clearly not ready for.
Within 5 Days he expects to:
- Find an effect (Stage Magic) he likes.
- Find out where to buy blue prints for the effect.
- Buy the blue prints.
- Wait for the magic shop to send the blue prints.
- Wait to receive the blue prints via mail.
- Read the blue prints, understand them, and work out materials needed.
- Buy and find these materials.
- Construct the prop.
- Test the prop.
- Perfect his act, work out a script and practice the effect and script.
- Get a friend to help with the act, and understand everything he knows relating to the effect.
- Get the prop to his school and find a place to store it.
- Perform the effect WITHOUT FAULT.
All within (Less) then 5 Days.
Maybe we sound 'harsh' but we are being completely honest and fair.
I performed at the Adelaide Fringe Festival and that took 4 Solid Months of practice and perfection (and construction.)
It is not possible, within his time frame.
Sorry man.
