Invisible Messages on Whatsapp Learn to do it!
Thousands of users of WhatsApp, one of the most used instant messaging applications in the world, have discovered a trick to send 'invisible' or 'transparent' messages to their contacts.
 
This trick has gone viral in recent days and has users wondering how it is possible to send this type of message, since it is well known that the application asks for at least one letter or one character to be able to send it.
 
The most logical option, apparently, is to open the chat or conversation where you intend to send the ‘invisible message’, either from a mobile phone or a computer, and press the space bar several times and then press the ‘send’ button.
 
However, this action is not possible since it is necessary, as mentioned above, to write a letter or a number in said message.
 
Thus, the real trick to send an 'invisible message' is to open the 'unicode.flopp.net' web page and then press the 'copy' button to effectively copy an 'invisible message', which you can 'paste' into any of the WhatsApp conversations and later send it.
 
The previous trick works in the same way using WhatsApp and without the need to install additional applications from the Google Play of Android or the App Store of iOS (iPhone) to send "Invisible messages".
