This weekend the wife and I were sitting on the patio ignoring each other, she on her smart phone, and me on my laptop. I was on Amazon searching for model wooden ships when I saw a wooden model steam locomotive. I emailed a link to my wife and she looks at it and then looks at what other people ordered with it. She found a track, a passenger car, and a railroad crossing.
Shows them to me and asks if they would be cool too. Heck yeah, right? Plays with her phone for a bit, then tells mne not to open any boxes that come over the next few days or I'll mess up my Christmas.
You can wind this thing up and it moves while showing you how the steam engine works. Doesn't require glue but I think I'll use it anyway.
