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.

Homemade glue

This is a non toxic, easy and inexpensive way to do child craft glue.

This needs adult supervision, remember that the kitchen can be a dangerous place to play in.

What we need:
  • 1/2 cup hot water,
  • 1 tablespoon vinegar,
  • 2 tablespoons of milk powder ,
  • 1/2 tablespoon of  baking soda,
  • water,
  • 1 coffee filter, 
  • 1 funnel,
  • a plastic/ glass containner,
  • 1 tablespoon,
  • plate.
How to:
  1. Mix the hot water and the powder milk until dissolves;
  2. Add the vinegar, the milk will form 2 distinct parts, the serum and the curds;
  3. Keep mixing this mixture until curds and serum are well separated;
  4. Place the filter in the funnel;
  5. Place the funnel in the container;
  6. Filter the previous mix;
  7. If necessary raise a little bit the funnel so the air can flow, remember that air takes up space;
  8. When the funnel is full "squeeze" the filter a bit, carefully;
  9. Discard the serum;
  10. In a small plate, using the spoon, break the serum layer into small pieces;
  11. Add one hot water teaspoon and about 1/4 teaspoon baking soda;
  12. Mix it all well until the adhesive becomes soft and more fluid;
  13. If the mixture is too thick add a little more water, if it has lumps add more baking soda.
  14. When not in use the adhesive covering it with transparent paper. 
With time the glue becomes more transparent and liquid. Trash the glue when it starts to smell slightly spoiled milk.

Note:
If the milk does not curdle try:
  • add more vinegar;
  • heat the mixture;
  • use more hot water.
Et voil√°!
you can almos eat it

Enjoy!
