Holiday season is the time that the children cherish the most and this is perhaps the right moment to teach them the all-important lesson of leading a sustainable life. If you are looking for a sustainable gift for your school going kids, this solar propelled monkey model kit will be an innovative present that will help them understand and value the power of alternative energy. Featuring a compact size (17x 8 x 2 cm) finished with ABS plastic body parts; the solar propelled kit comes with solar panel, motors and gears. All the kids have to do it assemble the various parts, following the assembly instructions, and place the monkey in sunlight. Once the solar panel is heated, the unit converts the solar power into energy to ascend the rope. You may get the green gift unit for £14.19 from Selectsolar.
