Please help me make ridges in my Fosters pot.

Hey what is the trick for doing the interlocking lids on the plastic containers?

Thanks,

George

Here are two example of the ziploc carry cases and the parts needed …

Once the center of the lid is removed ( you can also use a knife to cut out the center)
slip the resulting , threaded ring onto a ziploc container with a "snap-on" lid, on to the original screw-on container that you got the lid from to make the ring.

It is also possible to stack two of the smaller ziploc containers , one upside down
on the other , with both of the centers cut out of the lids, and simply glue (3M 90 Hi-Strength Spray Adhesive) one lid to another , thus allowing you to screw the containers into one another…
