Send us your questions
Some of our visitors have sent emails with interesting questions, we decided to start having a space to answer them. In this space the blog "Restless Minds" will answer all questions you send us
Send us your question for the email: Restless Minds.
Science progress affects our daily life and "to know" means you are going to chose right, because it allows you to form your own opinion on scientific everyday issues. On the other hand, having an elegant and harmonious vision of the world where we live in leads to a feeling of intellectual satisfaction.
We believe this kind of scientific day to day knowledge should be encouraged from an early age, and that's why this project was born: science, culture, knowledge, crafts for your restless mind.

DIY Pendant with beach stones
Another DIY project for the Summer.
Use your restless beach stone collection to make beautiful and personalized pendants. You can use them with chain-keys, necklaces or bracelets. You also can paint some lucky charms like the "Evil Eye"- in last picture-, this amulet will protect everyone who use it against the evil eye .
Or you can simply ask your restless to paint the stones as he wishes.
We will need:
- alcohol,
- little stones from the beach,
- thin wire,
- pliers,
- pencil,
- acrylic paints,
- varnish.
- Chose your stone, to paint evil eye the stone must be small, round and plain. try to chose the small ones, you will not want to use heavy weight around your neck;
- Clean the stone with tap water and alcohol to clean the salt, the sand and any other residue;
- Draw on the stone what you want to paint;
- Next paint all the stone with a light color, (white if possible);
- Next color your draw with the other colors, first the light ones;
- You must resist painting the details, Those will be the last thing to paint;
- Wait for 4h, paint must dry;
- Varnish and wait another 4h;
- Now you have 2 choices:
- Use the wire and make a cage for the stone: Use the pliers and curl the wire around the
stone. The stone must be trapped but not "glued" to the cage. When you finish make a double ring and super glue the 2 turns of the ring. - Make a double ring with the wire: Make a double ring with the pliers but don’t cut the ends, super glue the end tips to back of the stone.
- You can use this in many was: in a bracelet, in a necklace, in key chains...
Et voilá!
Another great use for beach stones
Enjoy!

Underwater candle
We learn here how water can work as a fantastic magical element in a illusion trick. Today we will see another heat transfer experiment, this time between water and wax.
We will need:
The candle in the empty bowl burns normally, as the wick is consumed the wax melt and the candle begins to get smaller.
The candle in the bowl with water burn normally until the wax reach the water level, here, or maybe a few mm before, the candle forms a "funnel", preventing water to contact with the wick, and the candle continues to burn for some time.
Why?
Both candles are consumed by the wick flame; if the candles are identical you can observe they burn at same velocity, until the water is placed in the equation.
Everything changes with the water. The candle is consumed because the wax is heated by the wick flame and as consequence the wax melts.
When we light up a candle we expect it to melt, but when we place it "under water" we expect the flame to go out.
But the true is: we can observe the candle burning underwater, it looks like the candle has a survival instinct, just like the balloon, and exactly for the same reason that the balloon doesn’t burst, the candle still burning, and we can see the formation of a "funnel" like a hole, surrounded by wax thin walls, protecting the wick from water.
This happens because the water is a good heat absorber; the heat necessary to raise water temperature by 1 degree is very high.
When the wick transfers the heat to the wax, the wax transfer it to the water, this allows the wax in contact with water to remain cold, and therefore solid.
This system is only in equilibrium for a few sec, or maybe a few minutes, but eventually the water will find its way, even because the walls will eventually collapse with the water pressure (weight) the water comes in and the candle sinks.
This is a demonstration, you can transform this in a experiment or science fair project:
Et voilá!
Sometimes things may defy common sense
Enjoy!
We will need:
- 2 candles, identical
- 2 tall bowls, higher then the candles and identical,
- match box, or a cigarette lighter,
- water, enough to fill the bowls.
- Chose a safe spot for the bowls. They will stay there for a while;
- Place the candles inside;
- Fill one bowl with water, leave about 1 in of the candle above the water level ;
- Don't fill the second bowl;
- Light both candles, this is an adult task;
- Wait several minutes;
- Let the wicks burn slow, The candle in the bowl with water will reach the water level;
- Let it burn for a bit more;
- Observe.

- Use diferent candle types (form, color, thickness, height) which of the candles keeps water away for longer?
- Vary water temperature; this helps the candle to stay lit for longer?

Decorated candle with beach stones
Another good application to your restless shell/stones collection is to do some candles. Doing candles can be a highly specialized task but it can be transformed in a very rudimentary task, anyway it's fun. To this DIY project you can buy a white and plain candle, if you wish
With this project you can recycle those annoying little crayons your restless keeps in his pencil box.
We will need:
- candle wax,
- candle-wick,
- old crayons,
- beach stones, tiny
- shells,
- an old pot or metal box, the box will be trashed after this, you can use a metal milk powder box for example
- Molds, the plastic yogurt cups work well they aren't the ideal material but they easy to find,
- Wooden sticks, you can use clothes pins.
- Wash and clean the yogurt cups very well;
- Cut the candle-wick with the cup height plus 2in;
- Chose a tiny, really tiny, stone to work as weight to candle-wick;
- Tie the stone to the wick.
- Tie the wooden stick to the other candle-wick end, the wick must be tied in the middle of stick;
- Place this “stick+wick+stone” set in the yogurt cup,
- The wick must be stretched, if needed adjust the knot on the stick;
- Place this cup in a metallic tray;
- Put the wax into the metal box and take it to the stove fire, don't use to much wax at the same time;
- Wait until the wax is pasty;
- Chose your favorite crayon color and chip it into the wax, keep the heat down during this process, this avoid the wax to become dark;
- Let the chips to dissolve and turn off the heat;

- Wait a few moments to cool the wax a little, remember you are using plastic yogurt cups and if the wax boil the cup will melt almost immediately, that’s why we use the metallic tray, to avoid accidents,
- Fill 1/4 of the cup with wax; place some stones against the mold wall;
- Place the wick on the center and far from the stones;
- Let it cool;
- Melt the wax again, you can chose to use another color, repeat the mix and the cool steps;
- Fill the cup at 1/2, place the stones, adjust the wick, and let it cool;
- Fill the rest of the cup with wax;
- Leave it to cool for 24hours;
- With the exact-O knife unmold the candle.
Original candles you can use as you wish
Enjoy!
