I know this has been done before (see Volcanic Picnic Plates by hpstoutharrow in outside: camping). I have to give him credit for giving me the incentive to put his idea on steroids (like Arnold S.) I just needed more room on my plate for more goodies! So here goes!
Step 1: Get a rally big plate!
I wanted more space on my plate for more food. I found out too many times at family picnics that if you don't get it the first time around, its gone! So enter the Picnic Plate on Steroids! I found a really big plate (platter) at my local and favorite Dollar Store, also some good size drink bottles.
Now trace the bottle mouth (top cap removed) ,underneath the plate in the center. I used a felt tip marker. Get out your trusty Dremel Tool fitted with a composite cutting wheel, (please: wear gloves & eye protection ) and carefully cut out the circle that you have just traced. Cut inside the line for a good fit. You can always remove more plastic for a nice fit but you can't put it back! It does not have to be perfect, as long as the bottle threads fit through the hole and the cap screws onto the bottle from above with the plate in between.
