Pyranine Based Decoation
Pyranine is a cool molecule which got the cool property called fluorescence. it means that when the molecule absorbs light in the ultraviolet region of the electromagnetic spectrum, it emits light in the visible. so we can see it brightly even if it's dark.
By reforming hot glue sticks containing pyranine and dyes, a spectacular sight was revealed.
Supplies
Hot glue sticks and gun
Marker pens
Baking paper
UV-A light source (such as LED)
Glue Melting
Six hot sticks in a pan was melted in the oven at 200C for 3 minutes.
Pyranine Add
marker pen's liquid dye, containing a pyranine was poured and stirred with the molten glue. We did it three times for each color we had.
Glue Sticks Reformation
The molten, colored, pyranine contained glue was poured on a baking paper and reformed to sticks shape so it could applied by hot glue gun
Scribbling Time
using a hot glue gun, we did some scribbling with the colored sticks on a baking paper. later on we arrange it decoratively
Turning Off the Lights
After turning off the light and apply UV LED, this amazing sight was revealed. now we just have to sit and look
