Cue the John Williams Jurassic Park theme music.
All kids love dinosaurs. If you meet a kid who tries to act all cool and deny this undeniable fact, you call them a filthy liar and show them a picture of the wooden dinosaur model they built and have proudly displayed in their room.
Alternatively, if you want to avoid antagonizing a small child (for some reason), you can just show them this picture of the talented Lehigh grad student Lisa Glover wearing a custom-made, 15-foot cardboard velociraptor costume.
I especially appreciate the scientifically accurate giant, googly eyes.
Bonus points: Glover has a (well-funded) Kickstarter so she can sell smaller versions of these little beauties. Of course, with all the money she's making, we hope she'll make the 15-foot version, too.
