Band Camp

Mogmatt's marching band played their show and then listened to it. They played the show almost perfectly and yet when they listened to it, it was all messed up. How could that have happened?


The band was hearing their echo. Because they were marching at the time, they were all different distances from the wall and their echoes played at different times.

Bird on the Moon

If a light oxygen tank were tied to a bird so that it can breathe on the moon, would the bird fly faster, slower or the same speed as it does on earth? (Remember that there is less gravity on the moon)


A bird cannot fly on the moon because there is no air to suspend it.

Water in the Cup

A man in a restaurant asked a waiter for a juice glass, a dinner plate, water, a match, and a lemon wedge. The man poured enough water onto the plate to cover it.
"If you can get the water on the plate into this glass without touching or moving this plate, I will give you $100," the man said. "You can use the match and lemon to do this."
A few minutes later, the waiter walked away with $100 in his pocket. How did the waiter get the water into the glass?

First, the waiter stuck the match into the lemon wedge, so that it would stand straight. Then he lit the match, and put it in the middle of the plate with the lemon. Then, he placed the glass upside-down over the match. As the flame used up the oxygen in the glass, it created a small vacuum, which sucked in the water through the space between the glass and the plate. Thus, the waiter got the water into the glass without touching or moving the plate.
