Introduction: How the Indians Looked for Holes in Their Bicycle Inner Tubes Part I

By

Sorry, I meant Native Calcuttains. ( spoiler alert: the   photo gives it away)

Step 1: This How I Find Illusive Tube Holes

Step #2  fill the tube with air (I use a pump)
Step #3 if step #2 fails, you have a leak.
Step #4 if step #2 succeeds  you could still have a leak.

Step #5 hold sections of the tube under water in the toilet tank.

It is fast easy  and has even worked in tanks  with floats
the last 6 lines are of use to some
I know,  I have had more hole in my tubes than I could lift.

first  look at  the tire  feel the inside for sharp things  warning: SHARP THINGS .
I use a small knife  and scrape and pull them out -use the distance  from the valve to look for  the  hole

if you can't pump fast enough,  stop and look for   the hole .   or twist the tube into an "8"and clamp down   so you're blocking  the air from  part of the tube  then let   the   "compressed air "  whoosh out  and  find the hole
