Now spray with the ammonia solution. The phenolphthalein will turn pink, the copper sulphate blue and the red-brown colour of the iron thiocyanate complex will almost disappear. This was kind of my baby," Bruns said about Magic Ink. "It felt like something nobody was working on yet, but something that I was really qualified to do.”

These can be used with younger children but the chemistry is more complex so the theory is best left to secondary age students. Most of the inks that become visible when you shine an ultra violet light on them also would become visible if you heat the paper. Equipment: Originally from Loveland, Dr. Carson Bruns wears several hats, including the role of an assistant professor of mechanical engineering with the ATLAS Institute at CU Boulder. He is also the co-founder, president and chief scientific officer of HYPRSKN, a company that licenses technology from the college. It has a brand called Magic Ink, a project Bruns has been working on since joining the staff at the school. These inks are best for younger children since most of the chemicals are household and generally less hazardous. They can be developed by heat generally ironing them with a hot iron or placing them in an oven or (on a white tile) on a hotplate. Equipment: That’s how you can excite people,” said Bang Bang. “It’s almost a Trojan horse into that new goal of how do we bridge the gap between tattoo and technology.” Now, reset the scales for a final time. Then, put the 4 and 2 Cups on the right of the scales. Then, put the 6 Cup on the left and fill it from the Blue Jar.Use their scientific knowledge to explain how changing the conditions the inks are under affects their visibility.

Why do we make pictures by writing code? How can artists draw data graphics, visual interfaces, and other Paint brushes used for painting models would be ideal. Alternatively, wooden splints could be used. When developed the message should be visible and readable so students should be able to inform others of the message. The message is given to another group who develops the message and reports to the group on what the message said.Phenolphthalein indicator solution (HIGHLY FLAMMABLE) – see CLEAPSS Hazcard HC032and CLEAPSSRecipe Book RB000. The spraying of potassium iodide with aqueous lead(II) nitrate involves the precipitation of bright yellow lead(II) iodide: thymolphthalein HIGHLY FLAMMABLE & HARMFUL, developed by sodium carbonate (Solid is IRRITANT – solution is LOW HAZARD) (or another base)
