Q. I'd like to draw on a chalkboard with chalk and then seal it so the art is permanent. What materials will I need? I see restaurants do it all the time and would like to create one. Thanks in advance!

A. Easy, there is spray laquer. You could remove it with a chemical remover but it is very permanent and can be wiped with water, etc. If you use a chalk fixative it can still be removed. You can buy laquer in a spray can for $3 at a craft store, Home Depot, Lowes, etc in matte or shiny finish. Rustoleum Painters Touch Spray Lacquer is one national brand that is easy to find.

What materials does an elementary school teachers use throughout the day?
Q. I have a friend who just graduated and is about to be looking for jobs as an elementary school teacher. I want to give her a little graduation/christmas gift and thought it would be nice to make a gift basket of materials or useful things she would enjoy using. I would love to hear what other elementary school teachers use supplies/material wise throughout the day, and what nice things at home would you also enjoy?
Asked by Ashley - Fri Dec 17 12:29:14 2010 - Teaching - 4 Answers - Comments

A. That is a great idea. To add to the list of the previous poster, I would include more name tags (you can never have to many), good sturdy scissors in different sizes, clear contact paper in a roll (from Walmart. etc.), clear packing tape rolls. I would avoid teacher inspiration books, the kind with quotes about how great it is to be a teacher. You can usually find them in the checkout or bargain section of B&N. Something that would really be helpful would be a great book on classroom discipline or a book for new teachers. My favorite is "The First Day of School" by Harry Wong. Try to avoid anything that the school may provide for your friend, i.e. pencils, white-out, paperclips, lesson plan books, chalk.

What materials do you need to build a balloon car?

Asked by Jessica I - Wed Jan 23 13:27:04 2008 - Engineering - 3 Answers - Comments

A. A ballon car? So I'm guessing you will be blowing up a balloon that is attached to your car, and using the air inside the balloon to make the car go, correct?? If this is the case, you want your car to be as light as possible and as friction free as possible. Perhaps you could build the car out of balsa, foam, or even an erector set. You obviously want your car as light as possible to require the least amount of force (from the balloon) to propel it. The friction comes in with the wheels/axels. You want minimum friction in your axel/wheel connection and you want very little surface area contact between the floor and the wheel - in other words, dont use thick wheels. You also want to use a brand new balloon (if you are going to race it)… [cont.]

A. PLus the under layment, which you ll need 2 100 s/f rolls you should get the installation kit , About 20$ This comes with a tapping block spacers and a pull bar. You also need basic power tools such as chop saw and a table saw. Everything can be done on the table saw , its just easier to have a chop saw. A skil saw and or a jig saw can also be used. You ll need a hand saw to under cut the trim and of course a hammer.And a basic utility knife for cutting the under layment. If your half way handy you can do this yourself. It isn t hard. Saving 300$ (+-) in the process. Any questions you can e mail me through my avatar . I ve attended several installation seminars as well as installed a few 100,000 s/f. GL

A. Vehicle - a marble. The track - Should be made from a decent sized wire/rod that is easily bendable but still able to hole its shape during the exhibition. You should make 2 rails, so as to support the marble during the course. Thise way you will only have 2 points of contact between the track and the vehicle and there should be very little drag. I would also recommend ignoring any major structure for the track and just support it at the low and high points along the course. To connect the rods, you should be able to either solder them together or epoxy them. Good luck.
