# Wave in a row of drinking straws

More than a dozen of drinking straws weighing $$10 \text{ g}$$ each are attached on a cellophane tape, evenly spaced, and the cellophane tape is fixed on the ceiling. If we flick the straw O at the center, then a transverse wave will be generated, propagating in both directions A and B. Which direction, A or B, will have a higher wave propagation speed?
