OK this is a twist on a classic brain teaser. First to answer EVERYTHING correctly BA. There is a glass that has a rock at the bottom. Without touching the rock or the glass or anything around it (the glass CANNOT move) how do you get the rock out? This is a two-part question 1. How do you get the rock out without touching the glass or rock or moving the glass? 2. How can it happen? Answer both parts... good luck

Here's mine: Can you pour water into the glass until it gets so full and the rock comes out with the water? This is assuming that the glass is sitting upright and the rock is lying inside the glass.

Pebbles however small still sink... but you are oh so close. Water/rock/float..... Put those together and you have it!

The rock could be a pebble, therefore be VERY light and flowing with the water out of the top of the glass.

this is just my assumption, but i really don't know how. Maybe the glass is in front and the rock is at the back. so if we are in front view, looking through the glass, we can see the rock which looks like at the bottom of the glass. But if we are on top view we can see that the rock is outside the glass.
