1.) any shell based blaster
2.)cheap bottle hair product.(i find garneir fructis hair cream has the best texture for shooting.)
3.)marker with the correct diameter to fit in the sawed off shell
4.) a knife to cut the shell to the right size
5.) Zip away weather sealant and tube applicator.
Step 1: The marker base and cutting the shell
First you need to get your marker and dismantle it
second you cut the very tip off and remove any furled plastic pieces around the newly cut edges.
now you are left off with one marker piece put it aside for now .
now it is time to cut the shell start cutting where the shell edges out then slopes .after cutting you will end up having to bore a bigger hole to accommodate the tube. push the marker in and apply zip away around the edges so it is air tight then leave the fully completed sludge shell in a lighted area and leave it for 24 hours.
