Hatching Tropical Fish Egg
Growing Pet - Color and Styles Vary
Put the egg in water and watch it hatch!
Simply put your egg into a container of water and wait 24 hours. By the end of the day you will have a hatchling. Remove the shell portion and place your hatchling into its own large container of water. Your small pet will soon mature to a full grown adult! They grow to 3" to 4". It'll be your very own pet and you don't even have to feed it! There are 6 different fish designs, so it will be a surprise when it hatches. Design and color will be chosen randomly at ship date.
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.
