I like to share how I made my kits and how they look with kids younger than me,but you do have to be careful.At our local show there was a kid that looked about 5 or 6 CLIMBING ON THE INTEMEDIATE TABLE around my models and my friends models.I was able to explain politly to the kid that doing that is not a good idea.At the end off the day my and my friend walked away with medals and mint models, and that kid walked away ready to build his first kit.Back to the subject, I think the best way to show a model to a "Energetic" kid is to have it on a turnable display stand and explain the kit.
