I bring for you one more learnings daily. I discovered by chance as a 9-volt battery is composed. I never stopped to think about it but thought it was a solid set. I replaced the battery of equipment and she, being worn out, opened in my hand. It was surprisingly when emerged 6 puppies AAA batteries. As the math does not lie, multiplying 6 by 1.5 comes to 9. It was not news to you? What a pity! I have been enjoyed the discovery. Maybe this information can be useful at some moment in life. Encourage curiosity in their children, sharing discoveries and most importantly, the association of ideas, transposed to other situations and find creative solutions.
ENCOURAGE THE CURIOSITY !!!
