Make an LED Throwie for 6 (six) cents - it's the cheapest Throwie ever!

LED Throwies are popular contraptions made of a battery, an LED, and a magnet all taped together. This version does not include a magnet, although it could.

This project uses the same principle as Tool Using Animal's Penny Battery and Brenn 10's Penny and Nickel Battery. It uses pennies as electrodes and vinegar water as an acid you make a battery that will power the LED.

The video that this is based on can be found here.

If you like penny batteries, you're going to love the 500 lb. potato battery.

what if you just get a a lot of batterys and make a unicorn so you become a penquin bounty hunter of the coast of mc donalds. mmmm.. but if you do the math in youre head youll come up with 5 trolls and the divide that by burger king and youll get one half a wizard of oz and 1 fourth 4th of a dorathy, lion, tinman and a scarecrow.

I'm somewhat confused as to the meaning of this message, but I'm fairly certain there were some questionable substances used in its production.

Euros won't work because you need both zinc and copper plates touching to work, such as inside a penny. Euros are made from copper and steel. Oh, if you dropped the e in penies it would... be rather amusing...
ScrapDaddy says: Jun 2, 2012. 10:48 PM
Also remembering that the plural of "penny" is PENNIES, with two N's.

Be sure that your pennies are dated after 1982, because they were almost pure copper before that date, if I recall correctly.
techturtle2 says: Jul 2, 2010. 8:44 PM
some pennies are compleatly steel because of WWII
jlking3 says: Jul 2, 2010. 9:24 PM
The only year that steel pennies were minted was 1943, but you are correct. :)
shaneomacmcgee says: May 19, 2009. 5:05 PM
'82 or '86, I'm not sure, but that's correct If you drop your pennies on concrete, copper ones "ding" in a higher pitch than the newer ones.

iglo1234 says: May 18, 2009. 9:14 PM
1.grab sandpaper 2.rub all over face 3.??????? 4.PROFIT!
bassclarinet23 says: Jan 10, 2010. 11:51 AM
5.) Go to hospital.
6.) Get skin graph.
7.) Tell everyone you were in a fire and saved 100 starving orphans, though you had severe burns on your face. (Sounds better than, "I was bored, so I grabbed the sander...") :)
8bit says: Apr 23, 2010. 3:07 PM
Step 7 is a face saving solution!

Rule 1 and 2.
daemonkrog says: Jun 21, 2010. 3:15 PM
Doesn't stating "Rule 1 and 2" break those rules?
iglo1234 says: Jun 21, 2010. 5:18 PM
Not if you don't know what it means.
daemonkrog says: Jun 22, 2010. 4:05 AM
Well I don't know what it memes.
iglo1234 says: Jun 23, 2010. 8:41 PM
