Emob Salt Water Giant Arachnoid Spider Robot Kit

Salt Water Giant Arachnoid is fun to build and exciting to watch as it scurries across the floor. Best of all, there are no batteries required, because this spider is powered by salt water. Since all of the pieces snap together, there is also no glue or paint required to assemble the robot spider. It is perfect for mechanically minded children looking for something that is challenging but not overwhelming to put together. Once it is fully assembled, kids will be surprised with the speed at which this spider can travel, which makes it perfect for scaring.Despite its large size, the salt water spider looks real until one takes a closer look.With a remarkably simple chemical reaction between salt water and magnesium, energy is created to bring the arachnoid to life. A removable fuel cell assembly slides into the spider?s rear section, so all children have to do is add a few drops of salt water onto it and slide it into place. The spider will immediately come to life by wiggling its legs. Even through the spider travels on wheels, the synchronized movements of its legs and its wiggling fangs give it a creepy crawly appearance. A few drops of salt water can power the spider for about 15 minutes at a time,but kids can easily open the rear section of the spider and add a few drops to the fuel cell for more play time.Since salt deteriorates the magnesium, there are two extra sheets included.Assembly Pro Tips:Only cut the plastic parts when you are going to use them. Their labels are on the sprues, and many of them look very similar and can be easy to confuse.When attaching the top of the spider, be very careful not to push on the wheels. Like me, you will have to open it back up and reinstall them, while being careful not to knock the legs or anything else out of place.Use very little water. Fill the plastic dropper about five times and squirt it into a small cup. Then add the salt. My arm is still tired from shaking salt into a full cup of water until it reached a 20% salt to water ratio.Use salt with a pour spout.The Salt Water Fuel Cell Giant Arachnoid has the following features:-All Plastic Parts are on 2 Sprues-Motor Assembly Parts-Plastic Saltwater Dropper-3 Magnesium Strips (Provide 5 to 7 Hours of Spider Crawling Time)-Removable Fuel Cell Assembly-No Batteries Required ?
