1. Why do some cakes rise and others don't?

One of the main phenomena involved in the rising of cakes is the production of carbon dioxide gas from baking powder. But, to achieve the expected performance, it's important not to add the yeast at the beginning of the preparation, pay attention to the expiration date and know the exact amount to use, not to place the cake mix in a cold oven, among other measures.

2. At what temperature can we die from heat?

Experts say that our bodies can collapse in heat. The problem is that the exact temperature at which this can happen depends on environmental factors, the age and health of each individual. But tests show that the risks begin when the temperature reaches 42°C.

3. How to prevent your soda from running out of gas?

When serving, the soda should be poured slowly and with the glass tilted, to avoid agitation. Ice, lemon and other ingredients increase interaction with rough surfaces, which also encourages the release of gas. In other words, it's best to avoid them. The best option is a very clean glass, as dirt also increases the loss of gas. Got some leftover soda? The solution is to Close the bottle as quickly as possible and put it in the refrigerator.

4. Why do insect bites itch?

Insect saliva is composed of a cocktail of proteins --anticoagulant, vasodilator, antiplatelet-- that facilitates blood absorption, but ends up causing an allergic reaction in its target (which in this case is you or me) and, consequently, the itching. What varies between one insect and another is the amount of these proteins.

5. What is the right way to stir coffee?
