I find it really useful when I need to weight small amount of things, like copper or sulfur for disinfect my plants.
Step 1: WHAT YOU NEED
-2 popsicle stick;
-2 pegs (like the ones in the photo);
-1 small carabiner;
-1 small keys ring;
-a piece of thread;
-1 short nail;
-1 small iron ring (I used one from the valve of the inner tube);
-2 small plastic bag of the same size;
-some bolts of different weight (1,2,5 grams)
Step 2: PREPARE THE STICKS
-draw a line in the exact middle of it (lengthwise);
-draw a line in the exact middle of the intact stick (crosswise);
-make 2 holes at the edges of the intact stick and one in the side of the half stick (like in the photo).
Step 4: PLACE THE CARABINER
Step 7: PLACE THE WEIGHT
Step 8: PREPARE THE WEIGHT MEASURE
Otherwise you can make small balls of clay of different weight.
