Hi Friends,
Found another interesting gadget!
This one is a X-Ray spray which can help you read the inside of an envelope without opening it.. Appropriately called the Envelope X-ray spray (from TelstarOne Communications.). this spray allows a person to see the contents as it turns the paper opaque or transparent. After 30 seconds, the paper is back to its original shape.. the makers claim that this spray leaves no marks!!
If you want to read confidential letters.... this one is certainly interesting!!
