So you don't have a gas jet in the garage? You don't think Margie and Ted are old enough to handle the high temperatures of a Bunsen burner? Our alcohol lamps are the answer. They burn alcohol (available at the hardware store), and are hot enough to boil water, to soften glass tubing for bending, and to generate the chemical reactions generally called for in science projects. The lamp is 2-1/2" x 2-1/2" x 2-1/2" glass bowl with a wick assembly that brings the whole to a height of 4-1/2" and comes with a handy little metal lid/extinguisher.
