Hi my friend gave me a mysterious 10 dollars and on the back of it there's a secret code hidden but theres something weird on it covering it what i don't know how to erase it. This is the picture i feel like its thicker than an actual dollar this is all i know. Could anyone help me solve the problem ? How and with what can i erase it?
Use household tools!
- Can you bend or fold the note? Is the layer brittle and does break off?
Can you scratch the layer off with a sharp blade?
Place the note between paper (kitchen roll) and use a hot flat iron. Does the layer melt?
Can you wash the layer off using a cotton bud and
- methylated spirit
- nail polish remover
Try dissolving it in ethanol or some kind of alcohol. Alcohol is polar so it would dissolve the cover if the substance is polar. The dollar bill is non polar and wouldn't be dissolved.
