Build a rack to hold your test tubes full of supplies ready for Kitchen Science.
Step 1: The Idea
I loved the idea and presentation of the front cover of Make:'s Illustrated Guide to Home Chemistry Experiments
The whole science-techno vibe is cool in a steampunk kinda way. Surely a test tube rack would be the most iconic image of a "science lab", and what better way to bring it into the kitchen than as a spice rack?
This gift was made for a relative, recently moved out of home, who is beginning to get into cooking.
Step 2: The Concept
I played around in Pro/Engineer, a 3D CAD program, designing a basic rack for the tubes. Commercial test tube racks are both expensive and not particularly attractive.
The width and thickness of the base and top peices was based on the scrap wood that I had lying around - re-use for the win!
This let me try out various combinations of row/columns, separation, and upper level height.
Step 3: Safety Gear
This step is applicable at multiple points of this instructable - wear appropriate safety gear for each peice of equipment
Step 4: Cut the Wood
Cut the wood you have chosen for the uppr and lower levels. I used a table saw, and cut two peices to size together to ensure they were identical.
I cut the two peices to 200mm length
Step 5: Clean As You GO
Again another oft-applicable step. Clean up as you go - it's easier in the long run. Do it after you make a mess in each step.
Step 6: Tape 'Em Together and Mark 'Em Up
Tape the two pieces together so that in the next few steps everything remains aligned. I labelled one end of both pieces to make sure I remembered which sides went together when I removed the tape.
Mark the centres of the test tube holes on the top level with a pencil. I used a 45mm spacing both vertically and horizontally.
