The kit uses 21 snap-together parts to build six different working models- including an airboat， a windmill， a puppy， and two different airplanes. An excellent beginner building kit designed to teach kids about solar energy in a fun way! <br>Please Note: The finished car is 2.5 inches long， 1.5 inches wide， and 2.75 inches tall when the solar panel is extended all the way up. The solar panel itself is 1 inch by 1.25 inches. <br>Build 6 different models<br>Contains a total of 32 small parts<br>Differs from other tropid model toys， they will move after assembled<br>Solar energy provide motive force<br>Do not need screws， so no tools is employed<br>Teach through lively activities<br>Solar battery life-span:3-5 years<br>Material: Polythene<br>Safe and durable<br>Age for:age 10+<br>Unit packing gross weight:160g<br>1 x Motor <br>1 x Solar power panel <br>2 x Gear <br>2 x Axle<br>1 x Adhesive sponge <br>4 x Wires <br>21 x Plastic pieces <br>1 x User manual<br>In original package<br /><img src="http://img6.eachbuyer.com/x6/p98/w646_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_5.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_6.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_7.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_8.jpg" />                                                        <img src="http://img6.eachbuyer.com/x6/p98/w646_9.jpg" />
