Build Your Incredible Machine - Gravity Lab would like to introduce our new range of gravity modifying appliances to be. Currently awaiting regulatory approval, we invite you to visit our testing facility and give them a go! We have prepared a selection of test scenarios for you and we are certain you can solve them! Please be aware that strong gravitational forces can cause a looming feeling of being observed! Never look directly at the emitted particles! While we tried our best to avoid the creation of micro wormholes, please never try to stack gravitational objects. All damages to the time and space continuum and all involved repair costs will be passed on to you!
