To measure the mass on an irregular object, you can use Water Displacement.
Water displacement is a way of measuring mass. Materials needed for this are:
A graduated cylinder
Water
Variable (Irregular Object).
Fill the graduated cylinder with a certain amount of water. Memorize it.
Put the irregular object into the graduated cylinder. Find the mass by subtracting the first amount of water from the second. That's your mass.

measuring tape, ruler, sticks, hand
You can use a tool called a Caliper. It will measure small objects (less than 6 inches) very accurately. For larger objects you can carefully use a construction tape measure.
