Science meets fashion head to toe in this do-it-yourself tie-dye lab! Kids just mix the dyes to create colors, then follow the steps to tie-dye groovy patterns—or invent their own method! As they invent, children will learn about the art and science of dyeing fabrics, investigate color mixing and explore human vision. Includes 24 pieces—2 nylon scrunchies, 2 pairs of nylon socks, 3 nontoxic dyes, a pair of gloves, 2 vinegar packets, tweezers, a beaker and 9 rubber bands—plus a full-color, 4-page manual; socks measure 2 1/2" x 6 1/2".
