Review on 🏗️ Mechanical Building Experiment Projects for Education by Jeffrey Dunn

My kids ages 10 and 16 had a blast putting this puzzle together with minimal help from me. The directions (pictures) were sometimes difficult to understand because the diagram shows only one direction. The saving grace is that the part numbers listed in the pictures helped (note the part number matches the panel it is mounted on and the panel diagram on the front. Another note: DO NOT remove any parts prior to the Assembly.As the part number is on the diagram on the front cover and in the panel letter.After assembling I had to experiment a bit to see which is faster, battery or solar powered.I like sets that encourage kids to think.
