Innovating Science: Polymers Kit - Making Flourescent Worms Allow students to learn about polymers and cross-linking using this fun and colorful activity. Students add a solution of sodium alginate to three calcium chloride solutions, each containing a different fluorescent dye. After a few minutes the liquid sodium alginate solution forms into gel-like polymer "worms". Upon completion of the activity, the worms may be placed under a black light and the students will observe their worms glow red, blue, and green. Contains enough material to make several dozen polymer worms. Kit Includes: Sodium alginate, 6g 0.1M calcium chloride/0.1% fluorescein, 1L 0.1M calcium chloride/0.04% rhodamine B, 1L 0.1M calcium chloride/0.5% quinine sulfate, 1L 3 Empty bottles w/flip-top caps 6 Forceps Materials Needed but not Supplied 3 Containers for calcium chloride solutions (such as beakers, glass jars, or plastictrays) Black light DOT Info: Non regulated Product Details Brand Innovating Science Manufacturer Innovating Science Product Type Science Lab Education Curriculum Support Mpn IS7045 Allow students to learn about polymers and cross-linking Students use soldium and calcium chloride to make gel-like polymer 'worms' Contains materials to make several dozen polymer worms Check out my other items. - Powered by

Arrived on time and items were exactly as advertised. The package was double boxed, and although the outer box was in pristine condition and marked as being fragile, there was minor damage to the inner box that did penetrate the cardboard. Fortunately, the glass items themselves were completely undamaged. Recommend inspecting any fragile items with the postal carrier present in the case that documentation is required. Otherwise, an excellent transaction!

Extremely happy with the box of rocks. I ordered the Moh's hardness kit, but they sent the Sedimentary box. I showed the seller a picture of the box. The seller (hbarsci) apologized and quickly sent the correct box without any argument or dispute. I got two for the price of one😍. Thank you 100%.
