Deluxe Materials is a company I was not familiar with. Deluxe Materials is based out of the Great Britain and it certainly provides with quality supplies to the hobbyists in Great Britain and beyond.

Liquid Gravity is a weighting system that can be used for different applications, from preventing a model airplane being a tail sitter, to balancing an RC airplane or even to providing weight to the rolling stock of your railroad layout.

I am not sure what metal is used for the tiny little "BBs", but it is not magnetic and after a few measurements I came up with a density of about 4.15 gr/cm3 (lead has a density of 11.3 gr/cm3 for comparison). Despite the lower density, "Liquid Gravity" it has a great advantage: it is nontoxic.

The size of each BB is less than 1-mm in diameter, so they are very small and can fill-in any crook and cranny in your model. At the same time, because they are so small, you have to be sure the volume to be filled has no small orifices for them to get out and end up scattered all over your workbench!

You can see short video describing different applications for "Liquid Gravity" at https://www.youtube.com/watch?v=uxeXA_QZVIc

Given that I was not familiar with this company and it is based out of the UK, I thought of linking to their distributors in the US: https://deluxematerials.co.uk/

Liquid Gravity is highly recommended to modelers of all skill levels. I would like to thank Deluxe Materials and IPMS/USA for the review sample.

Liquid Gravity is probably steel shot blasting abrasive

I did more research in trying to figure out what Liquid Gravity might be.  I believe, but can't guarantee, that it is merely steel shot used for abrasive blasting.  I bought some S170 size steel shot for comparison.  This appeared nearly identical to Liquid Gravity.  The same volume as a full bottle of Liquid Gravity weighed within a few grams of being equal.  It behaved magnetically the same.  The S170 size (0.0331" - 0.138" per one online sizing chart) was actually a little smaller than the Liquid Gravity.  While abrasive media is typically sold in quanitities such as 50 lbs or more, an eBay seller had it as "10 LBS - Cast Steel Shot Abrasive Blasting Media, Fine Grade, S170 Size" for $21.95 with free shipping.  That's 4,536 grams or about 19 times what comes in the 240 gram Liquid Gravity bottle.  Such steel shot is available in both smaller and larger sizes.  If you don't need much, the Liquid Gravity is certainly a convenient way to buy a little.  But if you want a lifetime supply, or perhaps enough for many lifetimes, it is much less expensive to just buy steel shot in bulk from one of the sources.  You can also buy steel shot on Amazon at good prices, but at the time I purchased, I found a little better deal on eBay.

Liquid Gravity IS magnetic

We started stocking this at a hobby shop I work on and I tested it with a magnetic.  It is definitely magnetic.  So if using in something like powered model railroad locomotives with motors that involve magnets, make extra sure none can get loose.
