On a quest for height

Adam is on a quest to grow tall. And not just over time, but within 3 weeks! Next month he turns 10 years old. For a long time he has wanted to go ride Go Karts. He hasn't been able to thus far due to his age (not yet 10) or his height. We will be in Arizona for a week in April, and thought he would enjoy riding go karts on his birthday. Unfortunately, the go kart establishments in Arizona allow riders by height, not age. He needs to be 56' tall. He measures at 54". When we measured him with shoes, he was 55". With that knowledge, Adam has been determined to help himself grow the extra inch in just a few weeks. His "appetite" has increased greatly in the first week of attempting this. He figures eating lots and lots of food at each meal will help him grow. He may have a point. But hopefully the growth will be in the right direction. :)
