Sponge-bob is admirable the work that, reminds me when I helped my children to make their models of work for school, that you have to be very thorough and detailed.
Or when I made my bracelets, sarcillos which is also very laborious.
I hope to see the final work, and I'm still trying to remember that there was a television series that named a lot a red corvette.
I used to work on cars all the time. Now I don't even drive but my kids love to learn about the inner workings of cars. Models is the best I can do for now. (next post is about a shooting range).
If children are curious and better to satisfy that curiosity with parents. My son plays a lot of mechanics, with imaginary cars, he wants to be a mechanic.
