2. You can certainly try your luck with a powerful vacuum cleaner. It is easier to fill the bottle with water. The ball will float to the surface, and you can take it without touching the bottle.
3. Turn on one of the light bulbs and leave it on for a few minutes. Then turn off and turn on the other one. Now we can safely go upstairs. The first light bulb turned on will be warm, the second one must be illuminated. Which means you didn't turn on the rest.

And knowing him, and the right time to get home.
5. The philosopher said to the brothers, “Exchange camels!”
