## #03: THE MISSING DOLLAR

Three people check into a hotel, pay \$30 for a room and immediately get into the room to get refreshed.
But the cost of the room is \$25. Thus a bellboy is sent to their room to return the remainder of \$5.
On the way to the room, the bellboy reasons that \$5 would be difficult to share among three people. So he pockets \$2 and gives \$1 to each person.
Now each person had paid \$10 and got back \$1.
So they paid \$9 each- totalling \$27.
The bellboy has \$2, totalling \$29.
Where is the missing \$1

## #02: A THOUSAND BOTTLES OF WINE

You have 1,000 bottles of wine, and exactly one bottle is poisoned. You need to find the poisoned wine before your party starts in an hour. You have 10 rats to test on to find out which bottle is deadly. The poison takes effect after an hour of consumption, so you only have one chance to run your rat poison experiment, meaning you can’t feed some rats wine and wait an hour before feeding them more wine. Assume each rat can drink as much wine as you feed it. How do you find the poisoned wine?

## #01:THE THREE LIGHT BULBS

In your cellar there are three light switches in the OFF position. Each switch controls 1 of 3 light bulbs on the floor above. You may move any of the switches but you may only go upstairs to inspect the bulbs once. How can you find the switch for each bulb with one inspection??

## Christmas style Paper Circuits!

We had a paper circuits workshop in December, and of course, we went with the Christmas theme! The group of bright young creative students all made christmas ornaments that light up!  They picked their design, chose their colors, and made the ornament. Then they learnt how light bulbs and switches work, and they applied their new knowledge to make fantastic, take-home creations. Here are a few in pictures.

Creative process is messy, and fun!

Lots of fairies and angels!

And here’s a blue nosed reindeer, because, why not!

Isn’t this snowman cute?

## Maker Faire Bengaluru 2017

Tinkerama exhibited at Maker faire 2017! It was as exciting as we thought it would be!

This was Bengaluru’s very first maker faire. It was held at Bangalore Palace, on Nov 17th and 18th. We turned up early on 17th and set up our booth.

Come 9am, people started pouring in. We had plenty of demos to show off.

The POV was a crowd puller! Here’s our POV in action, showing different messages on the fly.

Here’s ardoodler, making the most amazing doodles! Kids loved the doodling. We made buses and cars, trees and leaves, names and signatures. It was a lot of fun!

The magic lamps dazzled, as did the theremin. We also did a workshop on the Arduino theremin, and people loved it!

We loved connecting with the enthusiastic, fun crowd, and made lots of friends in the maker community! We hope to be at more such fairs in the future!
