 Introducing deluxe materials liquid gravity. Liquid gravity is a weighting product and consists of tiny non-toxic dense metal pellets. It's a far safer weighting alternative to lead-based products but it's just as heavy. In fact it's almost eight times heavier than water. Liquid gravity is designed to easily pour into an available space. It can easily be set in place using adhesives such as deluxe materials rocket hot glue or rocket card glue. So let's see liquid gravity in action. If you have ever built a model railroad car or locomotive you know that adding more weight and mass can help your rolling stock run reliably and can improve your locomotives pulling power. If you intend to add weight to close top rail cars the weight can simply be spread across the floor and fixed in place with rocket card glue as shown. When applying to the underside of an open top rail car such as a hopper gondola or flat car plastic strips can help contain the liquid gravity pellets. This will ensure that you don't obstruct the working of the car trucks just pour the liquid gravity into the contained area and level. Use a penetrating adhesive such as rocket card glue or rocket hot glue making sure that it soaks well into the liquid gravity pellet layer. The car weighed just under three ounces before we started and with the liquid gravity weight added it's now a bit less than half a pound. It may also be helpful to construct a styrene container that fits into a tight space and fill it with liquid gravity and glue as shown previously. Once the glue has set you have a custom weight of the right shape with no wasted volume ready to attach to your model. Liquid gravity is an excellent non-toxic alternative to lead based weighting products and as you have seen it's very easy to use. Liquid gravity is distributed through all good hobby shops by Walters, Horizon Hobby, Hobby Time and Heartland Hobby. You can buy liquid gravity directly from your local hobby store or online from Megahobby.com or YankeeTabler.com. Visit your local hobby shop and ask for deluxe materials liquid gravity by name.
