Grow A Bug

Growing Caterpillar - Grows 600%

Put the bug in water and watch it hatch!

Simply put your bug toy into a container of water and watch it grow. The caterpillar will grow 600% over 3 days. You can take it out of the water and play with it as it slowly shrinks back down to size. Once it dries out, you can place it back in water and watch it grow again. These bugs come in 6 different shapes and colors and will be chosen randomly at time of shipment.

Ages 5 & up

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. The Growing Creatures Book by Anne Linehan and Betsy Franco details measurement and data collection projects integrating math and science.
