My Hot-Air Balloon

Our children had a surprise visit from Magician Christine.  Magician Christine delighted the children with magic.  First, she place an empty tea bag on a flat tray, then she lighted it.  The teabag flew up, up, up in the air.  The children squealed at the sight of the flying teabag.  Then, in a wink of an eye, the flying teabag disappeared into thin air. Then, Magician Christine asked the children, "What air transport do you think it is?"  Elsa quickly responded, "A hot-air balloon."  This was a creative lesson the children enjoyed and learnt for the day.  Later, the children designed the hot-air balloon using paper and a blown-up balloon, straws and marker pens.
