fire from ice

The Boy Mechanic, vol. 1, page 338

Take a piece of very clear ice and melt it down into the hollow of your hands so as to form a large lens. The illustration shows how this is done. With the lens-shaped ice used in the same manner as a reading glass to direct the sun's rays on paper or shavings you can start a fire. - Contributed by Arthur E. Joerin.



“Therefore encourage one another and build each other up, just as in fact you are doing.”
1 Thessalonians 5:11
