Introduction: Pocket Abacus
Just in case you dont have a pencil and paper, calculator, or smart phone...
Step 1: Gather
1) 550 Cord 2) Measuring device 3) Scissors or knife 4) 15 Nuts, washers, or anything that will fit on the cord 5) Lighter (Optional)
Step 2: Measure and Cut
4 stands 1@18" and 3@12" just for some room to adjust
Step 3: Tie
Tie the 18" at the ends and slightly off center with the other 3
Step 4: Layout (Optional)
I laid all of them out because I didn't want two washers next to each other.
Step 5: Plan
Lay the 3@12" strands over the 18" strand and visualize where you are going to tie.
Step 6: Tying
Slide the top obect on and tie
Step 7: And More Tying
Slide the other 4 on, tie the bottom, and repeat for the other two.
Step 8: Cut and Melt
To give it a cleaner look and secure it a little better. Cut close to the knots, take the lighter to the ends, and blow it out.
Step 9: Finish
You are ready to take on the world of math... Well up to 999... This picture reads 369 if you weren't sure. Enjoy! Vote if you like!
