Cleaning Pennies
Today in science we did two experiments. Our second experiment was cleaning pennies
with coffee and vinegar. The teacher
used a butter knife to hit the bottom of a penny stack. The penny that was at the bottom flew and the
penny stack was still standing. I hope
we get to do more science.
Kaimen: What a neat experiment!
ReplyDeleteI would have thought the pennies on top would fall. Do you know why they did not?
