We have worked very hard to ensure all of our Gunge FX are as easy to mix as they are to use. Our Methylcellulose Gunge FX requires a Mixing Device. With a typical mixer you'll have quality Methylcellulose Gunge ready to use in under 5 minutes! The Methylcellulose powder can be mixed by hand to the same high quality, but this could take up to half an hour!

Please note, our mixing instructions are for MessySupplies approved products only and may differ between powders.

Choice of Thickness:

Methylcellulose Gunge FX is available in three different thickness options (Standard, Thick & Xtra Thick) which aim to meet everyone's needs. To give you are idea of the different thickness types, we have described the consistencies below.

Standard ~ Thin & stretchy. When poured from a height the Gunge FX will shape like an umbrella when hitting an object.

Thick ~ Dense & Sticky. Will stick to an object / body as it falls and appears more solid than the standard consistency.

Xtra Thick ~ Viscous & Opaque. Will feel heavy and clingy. When poured will move all at once.

Colouring your Mega Gunge FX:

If you require more than one colour of gunge, please see our gunge / slime powderWe stock in excess of 30 sensational colours. If you require a specific blend, colour ratio or colour match, please feel free to contact us and we will do our very best to fulfil your needs.

We also offer liquid colouring which enhances the visual appeal and presents a shiny, bolder colour. Our Vivid Enhancement Colouring (VECs) are recommended for studio filming, stage shows & streaky Gunge FX.
