I noticed this new phenomenon with our fairly new grand baby. Being born in 1945, I didn't have these things and neither did my kids, but modern kids, its a whole different world. They seem to have learned to push buttons to get a reaction. Lots of their toys do this. I had my camera out the other day and captured a sequence that showed yet another thing that must be kept in the kid-proof areas.
- Old remote control
- Old cell phone
Bill, my suggestion of "Making Toys that Teach by Les Neufeld - ISNB# 1-56158-606-4 (2003) " meets the criteria you stated. The majority of the toys in this book can be batched produced.I appreciate the responses, but these toys are for clients kids. I cant give them old cell phones, tubes, or cut up milk jugs lol. For my own thats fine. I was just looking for things I can batch out so I can make several at a time. I've made several animal rattles and the infants and toddlers like them. Im looking for toys for kids that are a little older. like 3-5. They need to be relatively quick, or something I can batch out to bring my time per toy down. If they are wheeled toys I would probably just buy the wheels to save time.
