Correct! The answer is Candle Wax.
I suggest you not to put them in your bubble tea! Rather, throw these candle pieces into a small jar, add a wick, and let it fill your room with a cozy, scented atmosphere!

Little facts about candles:

1. The first use of candle is probably dated 4 B.C. in Egypt, as clay candle holders were found.
2. The flame in a candle can reach 1400C. Even steel starts to melt under this temperature!
3. Refrigerating candles before use make them burn slowly, and last longer!
4. In the States, the retail sales of candles are estimated at USD$2.3 billion every year, excluding sales of candle accessories.
5. Although candles are no longer the main source of illumination, (thanks to Edison), more candles are used now than ever before.
6. The last name "Chandler" originates from the French word "Chandlier", which means candlemaker.
7. Paraffin Wax (the most common type of candle wax) comes from refined petroleum, from which gasoline is also extracted.
8. Beeswax (another common candle wax) is actually a refinement of honey, mixed with bee's saliva to give it a softer texture.

Making candles at home
The simplest way of making a candle is using sheet beeswax and wicks. They are easily found in craft stores. At room temperature, beeswax is soft and pliable. Simply roll the sheet of wax around the wick, but make sure the wax (especially the first layer) is tightly wrapped around the wick. And the less space between the layers of wax, the better the candle would burn. You can cut and bend the wax sheets into shapes you desired, or even try mixing and matching different color of the sheets. When you have had enough fun creating the funkiest looking candle, the last step is to make sure the different layers of wax are adhered. Use a hairdryer to heat your candle up slightly to blend the layers together, but beware that you are not trying to melt the wax.

This is probably the briefest introduction to candle making. There are many books and websites that you should check out if you are interested. A lot of skills and practice are needed to make a good, long lasting candle.

Answer: Flashlight
So what is so special about this flashlight? As much as you and I appreciate kinetic watches, this flashlight is hand-powered too. With repetitive squeezing and releasing of the handle, you will generate enough power in the motor to light the bulb up. Absolutely no battery required.

6. Did you ever have trouble finding a flashlight during a power failure? Some flashlights have light indicators allowing them to be found in the dark.
7. In 2002, a flashlight called Forever Flashlight was introduced. It requires no bulb, no battery, and is powered by shaking the flashlight tube. The company claims that 20 seconds of shaking can power the flashlight for 5 minutes. Instead of the traditional white or yellow color, the light emitted is in bright blue.
8. Stink-Finder is a type of flashlight which uses ultraviolet light to make animal contaminations and stains visible. It suits every dog, cat, squirrel, monkey, or whatever other pet that you keep. In fact, it works for babies too!
