It looks like someone has found old (from fifties) soviet children's book about engineers and is translating bits of it.

1. use soap on screws to screw them in easily;

2. cut the tennis ball in half and push pencil handle through the half so bristles are like inside of a cup which will catch paint drips when you are painting ceiling;

3. push small screw or nail through piece of hard paper so you can hold screw or nail in place and your fingers are too big to hold it comfortably, you can tear paper away later;

4. use vacuum cleaner, bit of cork and thread to get something through a hole in the wall;

5. when buying a bike, visit a couple repair shops and ask, which kind of bikes they see least of all;

6. and to crown all this, the master tip: when you are doing calculations on paper and your fountain pen runs out of ink plus your ink bottle is either empty or you just can't open it, use pencil to finish your work..

And so on and on, lots of tips, some better, some weirder, all to trigger little curious minds into wanting to become an engineer.
