    A clear glass whiteboard

    Update on using chalk markers on Lexan. The markers wipe off completely even after sitting for a week. If anything, they work better on Lexan than glass. One of the more interesting tests my son and I are doing is using the chalk markers on our flat LCD monitors. So far, the results are extremely good as the marker comes off easily and without any sign of ghosting. I have tried on several monitors, all anti glare, and it works for us. I am not recommending this as perhaps gloss screens act differently or some monitors may not have a glass surface. Do a dot test in the extreme corner as a test. Let me know if you have any issues.Tried it on my gorilla glass phone tho and it failed miserably as the marker would not "stick", just kind of makes blobs of the chalk, heh.

    Use Liquid chalk markers on glass, Lexan, and acrylic as they leave a much bolder marking than dry erase markers and come off easily:http://www.amazon.com/Chalk-Markers-Reversible-Cha...

    The Liquid chalk markers (of any color) work just as well on Lexan as they do on glass! Bold, bright, and easily read across the room. See below for the link to the chalk markers.Note that the chalk markers like to be store with the cap down to keep the wick moist. If they do "dry out, just press down on the marker tip to re-prime them.Good question about the chalk markers on Lexan. I tried the black and yellow on Lexan and they both work extremely well, MUCH better than dry erase markers. Strong dark lines with the black, and a deep color that pop out with the yellow. I wiped them off immediately and they cleaned up completely. I will let it sit for a week to see if there is any stubborn staining but I doubt it. I will reply next week if I DO have issues, if there is NO reply, ass...see more »The Liquid chalk markers (of any color) work just as well on Lexan as they do on glass!

    There are still a few clear tabletops at IKEA but they are quite narrow. The best place to buy glass now is for Glass Table top Protectors:https://www.google.com/search?q=glass+table+top+pr...With only $2.99 shipping, this is a good place to get tempered glass customized to your needs:http://www.dullesglassandmirror.com/glass-table-co...

    The best markers for glass are NOT dry erase markers. They are called Liquid Chalk Markers. Not for use on chalk boards, heh. I tried them and they work great.Blackhttp://www.amazon.com/Uchida-480-C-1-Regular-Bistr...Colors:http://www.amazon.com/Chalk-Markers-Reversible-Cha...
