Just enter “Meliza” into the search box and watch as your taken to a section of the planet where you can “chat” with a local alien. It’s just a chat bot, but it’s fun to try. Give it a shot.

Reformat Your Gmail Address With Dots
You can create multiple email addresses by simply adding a dot (.) anywhere in your Gmail username. Because Gmail doesn’t recognize dots as characters, messages sent to yourusername@gmail.com and y.o.u.r.u.s.e.r.n.a.m.e@gmail.com will all go to the same place!
Synonym Search With a Tilde
Adding a tilde (~) to your search terms will tell Google to include any related search terms or synonyms you mayhave missed. This improves your results page and can help find exactly what you’re looking for.
Beatbox With Google Translate 
It may sound odd, but typing a random string of letters into Google Translate, then hitting the listen icon will prompt Google to beatbox whatever you wrote down. Try it yourself by copy pasting “pv kkk pkkk pvpvpv ppkk pddd bschk bschk pv zk pv bschk pv pv pv bschk bschk bschk kkkkkkkkkk bschk bsch” into Google Translate and giving it a listen.
