How to make volcano


1.First make the 'cone' of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (more water may be added if needed).

2.Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape. Don't cover the hole or drop dough into it.

3.Fill the bottle most of the way full with warm water and a bit of red food color (can be done before sculpting if you don't take so long that the water gets cold).

4.Add 6 drops of detergent to the bottle contents. The detergent helps trap the bubbles produced by the reaction so you get better lava.

5.Add 2 tablespoons baking soda to the liquid.

6.Slowly pour vinegar into the bottle. Watch out - eruption time!


Chemistry is Cool :-)

Diet cokes and Mentos!!!  

Posted by Marlini


Wah!!! menarik apabila air bikarbonat seperti coca cola apabila diletakkan Mentos ia akan menghasilkan tindakbalas ledakan air cokes seperti air pancutan.

Pada tahun 2006 program Mythbuster pada Discovery Channel telah mendapati kafein, potassium benzoate, aspartame, dan CO2 yg terkandung dalam coca cola diet dan gelatin serta bahan arabic dari mentos menyebabkan kesan atau effectjet” atau ledakan apabila kedua-dua bahan tersebut bertindakbalas.

"Experiments in a 2006 edition of the Discovery Channel programme Mythbusters suggested the chemicals responsible for the reaction are gum arabic and gelatine in the sweets, and caffeine, potassium benzoate and aspartame in the Coke."



Bagaimana tindakbalas ini berlaku? Jom baca!!

"The physical structure of the Mentos is the most significant cause of the eruption due to nucleation. When flavored Mentos with a smooth waxy coating were tested in carbonated water, no reaction occurred, whereas standard Mentos added to carbonated water formed a small eruption, affirming the nucleation-site theory. The surface of the mint Mentos is littered with many small holes, allowing CO2 bubbles to form very rapidly and in great quantity, in turn causing the jet of foam. This was further supported when rock salt was used as an effective substitute for Mentos."

*Jadi anda boleh la mencuba untuk melihat hasil yang sebenar dan berhati-hati semasa melakukan eksperimen ini. Selamat Mencuba!!
