make this amazing syringe generator in just 15 minutes. you will require a sterilised
brand new syringe, two very strong neodymium magnets, an LED and lots of copper wire. first
remove the needle part of the syringe....remove the plunger, remove the rubber piston. then
take very strong magnets which are loose fit in the barrel of the syringe and then put
the rubber piston in place as the end cap. the magnets can move freely inside the barrel.
now on top of the plastic band of the syringe wind 500 times of insulated copper wire, very
thin copper wire, this is the part which will take maximum time. now take the two ends of
the insulated copper wire and remove the insulation from both these ends and attach these copper
wire ends to an LED. this is because that LED draws very little current. now your project
is almost over. you can see the perspective. now if hold the syringe in one hand and move
it side ways you will find that the LED lights up. both the magnets move and they create
a varying magnetic field, lines of forces occur and a small current is generated which
is just enough to light an LED.
