  1. Slapping the remote is not a sure-shot way of making it work.<\/span><\/li>\n
  2. But the “technique” does work sometimes, and here is the science behind it.<\/span><\/li>\n
  3. Because batteries sit in remote control for months or even years, an oxidative layer forms between the battery’s negative terminal and the terminal (spring) of the remote.<\/span><\/li>\n
  4. Forming of the oxidative layer, i.e., oxidation<\/a>, is the same process that leads to browning of the apple or rusting of an iron bar.<\/span><\/li>\n
  5. The oxidative layer has the characteristic that it blocks the flow of current.<\/span><\/li>\n
  6. Now, if the remote control used a lot of power, it would easily overcome this resistivity posed by the oxidative layer.<\/span><\/li>\n
  7. But remote controls use small amounts of power, and so, an oxidative layer is enough to hamper its function.<\/span><\/li>\n
  8. When we slap the remote, the batteries inside move slightly to disturb the oxidative layer.<\/span><\/li>\n
  9. Small power (point 7 above) also explains why slapping is more often required in the case of old batteries (even less power).<\/span><\/li>\n
  10. As the resistivity weakens, the remote control starts to work again.<\/span><\/li>\n<\/ol>\n
