Forget chocolate bunnies for a moment. This upcoming Easter season, I decided to try something a bit more… prehistoric. I was given a freebie egg to review.
My mission: to hatch the Giant Hatching Dinosaur Egg from Rex London. The product promises a simple process: submerge the egg in water, wait about 48 hours for hatching to begin, and watch your dinosaur grow to full size over a week.
But does it deliver? Here’s my experience.
First Impressions & Setup:
The egg itself is impressively large. My first concern was shipping – it feels like it could be fragile, and I worried about it arriving cracked due to its journey to me here in Scotland. Thankfully, it arrived intact.
The immediate challenge, however, was finding a suitable container. This egg is big, and requires full submersion. My largest pasta bowls weren’t even close. Be warned: you’ll need a basin or bucket with some serious capacity. This was probably the trickiest part of the whole process!
The Hatching Experience:
Once submerged, the egg performed largely as advertised.
- Timeline: Within a day, small cracks appeared, fulfilling the ~48-hour hatching window promise. Soon after, the first glimpse of the dinosaur emerged.
- Mechanism: Interestingly, the egg didn’t dissolve or break apart completely. It cracked significantly, but the dinosaur needed some manual “help” (a gentle ‘medical intervention’, if you will) to emerge fully. This actually added a weirdly realistic touch, especially with the ‘egg slime’ coating the newly hatched creature!
- Engagement: While the process takes days, checking the progress each morning was genuinely engaging for me as an adult. It became a slow-burn science experiment unfolding on the side table.
The Result: Dino Growth!

The dinosaur definitely grows! The creature that hatches continues to expand over the following week, absorbing water. The final size was considerably larger than the egg itself – I’d estimate the hatched T-Rex was about three times the size it must have been packed inside the egg, which is quite impressive.
Evaluation: Pros & Cons
So, how does the Rex London Giant Hatching Dinosaur Egg stack up as a product?
Pros:
- Delivers on Core Promise: It does hatch, and the dinosaur does grow significantly, providing a satisfying payoff.
- Engaging Process (for some): For patient observers (like me!), the slow reveal over a week is quite fascinating.
- Good Novelty Factor: It’s a fun, quirky item that certainly sparks curiosity.
- No Actual Dinosaur Rampages: Always a bonus.
Cons:
- Container Size: The need for a very large container is a practical drawback.
- Potential Fragility: While mine arrived safely, the risk of shipping damage seems plausible.
- Slow Pace for Kids?: The week-long process might test the patience of younger children expecting faster results.
Final Verdict:

The Rex London Giant Hatching Dinosaur Egg is a fun novelty product that largely delivers on its promise of hatching and growth. It provided me with a genuinely enjoyable week of observation. However, be prepared for the practical challenge of finding a container large enough and the slow pace of the experience.
Recommended for: Patient adults, older kids interested in dinosaurs and science experiments, or anyone looking for a quirky, non-chocolate gift. Just ensure you (or the recipient) have a big enough bucket!
