Fun for Future Engineers Hands-on construction and creation of
four simple machines is a fun introduction into building and the
mechanics of hydraulic machines. Using all pre-cut pieces, glue,
and simple instructions, you can make a Platform Lifter, Scissor
Lift, Cherry Picker, and Excavator. The Platform Lifter provides
an excellent example of how we use technology to move people and
materials around. The Cherry Picker is similar to the ones often
mounted on truck beds to steadily lift people and parts to great
heights. The Excavator kit uses first and third class lever like
the ones used in trucks at most construction sites.The Scissor
Lift kit uses the same principles and construction that is
common to industrial scissor lifters. Each hydraulic model uses
water instead of hydraulic fluid. No batteries are needed to
power these models. For ages 8 +. Warning: Choking Hazard -Small
Parts. Not for children under 3 years.
