The demonstrations provide the interest and excitement that most of us only dream of generating through our eloquent and passionate speech. What does help is an uninhibited presenter who is willing to try things that are a bit unusual. A funny costume adds to the atmosphere. Tuxedos can be purchased at surprisingly low prices when formal-wear stores have their periodic clearances. A dramatic entrance and exit are good.
Audience participation is important.
Children will always volunteer to assist with the demonstrations. Live music, or even tape- recorded music, and sound effects are good additions. Special guests in the audience or surprise visits by historical figures add a delightful touch. We have invited local politicians, university administrators, and local television personalities. Isaac Newton and Albert Einstein have paid unexpected visits.
