Table and light measurements

I came across this lightbox which is in pretty rough shape, It is in the old printer room in the dungeon, I don't think anyone would mind us using it...
I might ask the custodian if we are able to use it, I'm not sure who else we would ask???

The surface is 100x70 cm, I think a good way of blocking out the light (except for were the bottles sit) would be to get sheets of 3 or 6 mm MDF and laser cut holes the size of the bottle base. This would mean that the bottles would be a little more stable too, which is good.

Here is the size of the bottles, I will make up an illustrator file of what the boards will look like and cut it out soon. 

We decided that the optimum layout is to have 15-20 bottles arranged in a triangle (like ten pin bowling).
