Looking for any information or ideas on a way to build a relatively inexpensive and portable/storable gunge tank for the house. Ordered some gunge from messy supplies and want to use it!
You can get some great results with a pretty simple setup - just a plastic storage box with a bung / bath plug / water balloon stuck in a hole works well.
The biggest consideration is how you suspend it. A storage container full of gunge is going to weigh 20-40kg, so make sure whatever holds it is up to the job!
I know someone who fashioned one out of an old shower cabinet, a box and some PVC pipes. I know that idea wouldn't be very portable but it was very cleverly done. Might be something to consider
