Ignite: Personal Finance Style

For my non-college intending classes, I'm going to try to have them create an Ignite style presentation fr a final project. they need to choose some topic we've covered this term and  make a presentation on it. I've told them they can choose what they do, but they need 20 slides auto changing every 15 second and they need to give a talk at the same time. I suppose I'll need to make allowances for those students to shy to stand up. Record a Voice over ?
