pletely foreign to the small-scale blaster. However, the blast design principles and techniques that work for six-inch holes, 50 feet deep, also work for 1.5-inch holes that are six feet deep. It is simply a matter of scale, and the blaster will find that the hole diameter (i.e., the limit on explosive load per foot of borehole) is the

Do the same using the coin. If the rock is softer than both, try to scratch it with your fingernail. This is a quick and simple version of the 10-point Mohs scale of mineral hardness: steel is usually hardness 5-1/2, coins are hardness 3, and fingernails are hardness 2. Be careful: a soft, crumbly rock made of hard minerals may be confusing.

Modelers score and snap the tile, then glue and stack it so the broken edges face out. Sculptamold or plaster fills in the gaps and utility knives and wire brushes texturize the rough edges, then paint and stain makes it look like rock. Stacking the pieces so there are obvious layers works well for a quarry scene.

If the water line moves up 3/4 of a cup then that's how big the rock is. You can use Google to convert that volume to cubic centimeters.
