Description: This is a chemistry demonstration in which different salts are heated in a flame to produce rainbow colors. I've got instructions on sciencenotes.org listing the chemicals I used and how you can replicate the effect yourself. Or, you can save yourself the sound of the smoke detector and just enjoy the image. The salts show up in most product options, but I cropped them out for the skirt.
Description: Here's a simple periodic table with all 118 element symbols. The element groups are rainbow colored circles. This table doesn't have all the facts and figures. The goal was a bright, colorful table that was easy to read. I've got lots of detailed periodic tables, including one with round element tiles, if that's your thing. This periodic table has a transparent background, so if there is a particular color you'd like to see, just let me know.
