Find the average number of pennies one type of pretzel stick can hold. Test to see if it makes a difference if you drop the pennies in the bucket or if you place them in gently, using the tweezers or chopsticks. Record your results. Try pretzels of various lengths and widths to see what size and length hold the most and least pennies. Try testing uncooked spaghetti to see how it holds up in comparison to the pretzel sticks.
Questions Look at the ends of a broken pretzel with a magnifying glass.
