The Boat at High Tide

A boat has a ladder that has six rungs. Each rung is one foot apart. The bottom rung is one foot from the water. The tide rises at 12 inches every 15 minutes. High tide peaks in one hour.

When the tide is at its highest, how many rungs are under water?

None. The boat is floating on the water, so as the tide rises, so does the ladder.

You Melted My Ice

A full glass of water with a single ice cube sits on a table. When the ice has completely melted, will the level of the water have increased, decreased or remain unchanged?

The water level remains unchanged because the ice cube displaces its own weight. If you’re not convinced, read Archimedes’ Principle, which states that any floating object displaces its own weight of fluid. Still not convinced? Here are a few more sources.

How to Save Gas

If you could chose to increase the average fuel economy of a car, which of these would save the most fuel?

1. 10mpg -> 12mpg
2. 12mpg -> 15mpg
3. 15mpg -> 20mpg
4. 20mpg -> 30mpg
5. 30mpg -> 60mpg

It turns out they all save the same amount of fuel.

If you travel 100 miles:

100 / 10 = 10 gallons used
100 / 12 = 8 1/3 gallons used

10 – 8 1/3 = 1 2/3 gallons saved

100 / 30 = 3 1/3 gallons used
100 / 60 = 1 2/3 gallons used

3 1/3 – 1 2/3 = 1 2/3 gallons saved

Travel a Lot Meet Both Rich and Poor

I travel a lot and meet both the rich and the poor, but nobody knows where I am going next. I’m invisible but you can see what I do. Who or what am I?

Wind (or anything blown by the wind). It moves all over, reaches the rich and the poor equally and no one knows exactly which way the next gust of wind will blow. You can’t see the wind, but you can see what it blows, like leaves or dust.

Turd Station

At Coney Island (the amusement park in Ohio) over Memorial Day weekend I saw a changing station in the men’s bathroom. A clever fellow had scraped off some letters to make the changing station read, “Turd Station”. What was the original name of the changing station?

sTURDy Station2, by Rubbermaid.

Here’s a picture of one without the letters scratched out.
