I searched everywhere and could not find a thread for brainteasers or brain games so here we are.
I thought this one up just for preppers that do a lot of canning:
You have no measuring cup.
But you do have 2, clear-glass quart jars that have only the full mark on them that says "1 Quart" (4 Cups). Since they are clear, you can 'balance the levels' by pouring from one into the other until they are exactly the same level.
Did you know using only your brain, some math, and only those 2 ungraduated jars, you can accurately measure the following amounts?
1-cup, 2, cups, 2-1/2 cups, 3 cups, 3-1/2 cups, 4 cups, 5 cups, 6 cups, 7 cups, 7-1/2 cups and 8 cups.
Ok, the 4 cup and 8 cup measurements are gimmies so we'll leave them out.
I'll get you started:
Step 1: Fill the first one to the mark and you have 4 cups. Pour from the first jar into the second jar and balance the two levels. You now have 2 cups in both.
Step 2: Pour the second jar back into the source and repeat 'balancing the levels'. You now have 1 cup in both jars.
Can you figure out the rest?
