Giant Growing Dinosaur
Item #: WSGB-500
CLEARANCE - While Supplies Last

This item is discontinued - available while supplies last.

You might say we're addicted to growing creatures and these are amazing! Each dino starts out measuring 13 cm (5 in) long before you soak them in water. Watch out! This dino will grow to an amazing 36 cm (14 in) long when it reaches its full size. If you're extremely patient and careful, the super-size dinosaur can be dried out and it will shrink down to its original size. Very cool! Ages 3 and up.

How does it work?

Just add water. Let your dino sit in the water for one week and watch him grow to a whopping 14 inches!

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.
