Our fan Andrew O. asked, how much can you grow *overnight*? For starters, you stretch about 1/2 inch every night, but shrink back down 1/2 inch because of “gravity” pulling down all day and smushing your body. Astronauts actually grow up to 2 inches when they float in space. But on top of that, your bones might grow really fast for short bursts, up to 1/2 inch in one day or night!

*Wee ones:* Find the tallest thing in the room that’s shorter than you.

*Little kids:* Who’s the tallest person in your family? How many feet taller than you is he or she? Find out your height to the closest foot. *Bonus:* If you grow 1/2 inch overnight AND stretch another 1/2 inch, how much taller are you in the morning?

*Big kids:* If you grew 1/2 inch every day, how much could you grow in 1 week? (Hint if needed: How much could you grow in 2 days, then in 4, then in 6…) *Bonus:* If you grow 1/2 inch each month, with your first in this month (November), in what month will you be 3 inches taller?

__Answers:__

*Wee ones:* Answers may include a bedpost, a chair back, or a baseball bat leaning against the wall.

*Little kids:* Different for everyone…find out that person’s height, then subtract your own. *Bonus: *1 inch.

*Big kids:* 3 1/2 inches. *Bonus:* In April, since you need 6 monthly spurts including November.
