I have done a few basic ones on my @article61 profile and have some on my @team-solutions profile too. I would like to start building a framework around these videos to give them some direction and will be asking for advice when I attend the steemit meet in Birmingham on the 7th April. Hopefully get some good support and I can start the project off properly. My vids are not catered for children at the moment but I have done lots of volunteer work with kids and I think I could narrate an age appropriate video. The timing of an engine is a fascinating thing when it is displayed properly and I am sure kids would be interested. Like I said, let me know if you are interested in working together and if I have your support I will do a tutorial for kids.
