Price is each. Put this lizard in water and watch it grow! Assorted styles, yours will be chosen at random from stock but if you buy more than one, we will send a variety. This Ginormous Lizard grows up to 36 in length. Seriously BIG FUN! These lizards are 12.5 inches long before you soak them in water-36 inches when they reach full size. (a yard long). Think of the fun you can have putting that in someones bathtub! Also, this is a fun way to teach measurement. Can be dried out and then grown again. We tried them and were amazed how big they grew. Put your grow lizard in a tub or bucket of cool water and watch it grow! It will keep kids interested in how much they change day to day. Build them a home, they will never dissolve or turn to mush. Growing animals and other things (brains etc!) that are made to increase in size in water are made up of two polymers. One is poly(vinyl acetate) which keeps the original proportions and shape of the item or creature and the other polymer is polyacrylamide which is the super absorbent polymer. The growing creatures have many teaching applications in science and math, including graphing, drawing conclusions, and measurement using linear, mass and volume.
