You need a lot of patience and time (100 years might be enough). First of all, the glow-in-the-dark skeleton would not go together (we've put together many other dino skeletons) so we gave up on that. Next, my 8 year old grandson & I did not find it rewarding to peck away at a hard lump and rarely find a "bone". To speed things up, I used a screwdriver--we got to the point where we'd be happy just to find a few bones. By the time we were done "digging" we realized there was no way this thing would stay together even with super glue. This granny is done with dinosaur digging kits!
