i need an idea for a demonstration speech?
some demos my classmates did were how to do a card trick, how to make silly putty, etc. Any ideas?
How about how to fold a paper crane. It will take a little practice on your part and go to class prepared with enough copies of paper cut in squares. If you can get to Walmart or a craft store and buy a package of precut origami paper it would be even better. You will find many sites that will show you how to do it.
