wanted a pet Dinosaur? Watch in awe as your jumbo dino egg hatches into your
favourite prehistoric creature when submerged in water. Then watch, as your cute
6-8cm dino hatchling grows to a whopping 5 to 10 times its
original size! It works like Magic, but the secret to these growing wonders is
that they are made out of a special superabsorbent polymer that soaks up water
like a sponge. The polymer, or hydrpgel, is similar to the non-toxic chemical
used in baby nappies. So dont overlook the educational value of these popular

does it work?
Completely submerge the speckled
dino egg in a container of water. Within 12-24 hours the egg shell will crack
and your baby pet will begin to hatch. Then watch your 5-8 cm baby dino grow
into a 40cm monster over the next couple of days. To take full advantage of the
science angle, take some measurements of your new born hatchling. One
of the easiest ways to take measurements is to place the baby dino on a piece of
graph paper and trace around it. Simply count the squares to determine the area
and size of the object. It's
fun to watch your dino grow for the first 24 hours... but don't be disappointed
if it's not huge. It takes about 5 days for it to get really big. After 24
hours, remove the dino from the water and carefully dry it off with paper towel.
Take measurements and record your data on your graph paper. Back to the water
they go for another 24 hours. Continue gathering data until the creatures stop
growing after about 7 days.

did it fall apart?
your water is too hot, it will cause the creatures to disintegrate. Warm water
works best, but make sure that it isn't too hot.
long will it last?
long as the creatures are handled carefully, they will last for a long time. And
because it is reusable, you can dry it out and regrow it several times.
long does it take to grow to its full size?
