Chromatography Paper Sheets, Grade 1 - 100 x 300mm
Colours from sweets like Smarties or M&Ms or from water-based felt-tip pens split into their separate dyes when the chromatography paper absorbs water. Just how few dyes does it take to make all those sweet colours? Which was the pen that wrote the unsigned letter? Your children can be the detectives!
Supplied in boxes of 100 sheets.
Size: 100 x 300mm.
