Giant Growing Cobra
Item #: WCOB-500
CLEARANCE - While Supplies Last

This item is discontinued - available while supplies last.

Our collection of growing creatures just wouldn't be complete without a growing cobra and this one is huge. Before putting the snake in water, it measures about 46 cm (18 in) long. But it grows to almost 1.5 meters (5 feet) long! You'll learn the secret to the growing snake in the enclosed instructions and even get a few ideas for a science fair project. Just remove the snake from the water and watch him shrink back down over time. Plus, the polymer that makes these creatures grow is an example of amazing Hydrogels... superabsorbent polymers that are saving the environment. Recommended for children ages 4 and up.

What's included?

  • 1 Giant Growing Cobra in assorted colors

How does it work?

Just submerse the giant growing cobra in warm water and watch as he grows into a giant creature. The process may take quite a few days, but the results are worth the wait. The snake can also be taken out of the water and allowed to shrink back to his original size.

Product FAQ

  • Why did it fall apart?
    If your water is too hot, it will cause the creatures to disintegrate. While warm water works best, make sure that it isn't too hot.
  • Why does it have a hole in its belly?
    The hole is to let water into the creature, since it is hollow, and allows all sides of the polymer to grow evenly.
  • How long will it last?
    As long as the creatures are handled carefully, they will last for a long time. Since you are able to take it out of the water and have it evaporate, you will be able to regrow it numerous times.
  • Why is it “leaking” polymer?
    The skin is packed so tight that some excess tends to leak off.
  • How long does it take to grow to its full size?
    About a week and a half to two weeks. It makes the perfect activity to measure every day to see how much it has grown over one day.
  • Is it reusable?
    Absolutely. Take the creature out of the water and, depending on how humid your climate is, it should take about 3 weeks to a month to shrink to its original size.

Fantastic

I have used this product in my classroom for the last two years. The kids love it and it is a great way to teach them about measurement.
