Dear Amy: What's another way to clean the bathtub without using toxic chemicals? — Henry, Calgary, Alberta, Canada

Dear Henry: Many people create their own cleaning products out of basic ingredients such as vinegar, baking soda and soap. Not only are they easy to make, they’re also better for the environment than commercial cleaners. You can create a soft scrub to clean the bathtub by combining 1/2 cup of baking soda and 2-3 tablespoons of liquid soap. You can also use this scrub to clean the sink and tile surfaces. For more natural cleaning recipes, check out www.ecocycle.org/hazwaste/recipes.cfm. Your bathroom will be sparkling clean and green!

Dear Amy: What is the last number ever? — Khylle, New York

Dear Khylle: It might sound weird, but there isn't one! Think of any really large number you want. It might be thousands of digits long, but it can always be made bigger by adding 1 to it. See the problem? Learn more about really large numbers at http://mathforum.org/dr.math/faq/

. You’ll even learn about infinity and what a googol is. (Hint: It’s not an Internet search engine.)
