Karmen's Krazy Khristmas

With only a couple of weeks until school starts, Karmen decides she wants to see her grandparents, but they aren't coming until Christmas. It's too far to travel to their house in Missouri right now, so she decides to make a time-travel machine and have Christmas early at her house.
After finding the materials she needs in her house, she begins her work. She can't believe it when the time machine actually works.
Karmen's "Khristmas" is in for many surprises. That is why she calls it Karmen's Krazy Khristmas. All the relatives come as well as cold weather, ice, and snow. This weather is very unusual for Houston, Texas.
The cousins decide on a snowball fight. Karmen and Allison find a way to make colored snowballs. They are very surprised to find out what happens to Emily and Christopher when the snowballs hit them.
Karmen's parents leave it up to her to figure out how to solve the problem. Being the clever person she is, she finds a way.
