And then you can make cool photos and pretend to study low speed aerodynamics like the ones included here.
OBJECTIVE: be able to conveniently hold conventional laser pointer push button without applying continuous pressure yourself.
NEED: some tape (L_tape>=2pi*D_laser);
a toothpick (or a similar shaped/thickness pin of any kind);
and a conventional push button laser pointer.
P.S.: This is my first instructable, please be gentle.
Step 1: Tape
Then put another layer with the sticky side inward (so no outer surfaces are sticky at all) around the first ring.
Finally slide it on the laser pointer, covering the evil push button.
This should not activate the push button and you should be able to use your laser pointer as before.
Step 2: Pin
It would be best if the toothpick can stay in there just tight enough so that the push button is not activated while the pin is not sliding out easily.
