My daughters class has to make an erupting volcano using diet soda and mento's candy....can anyone help.?

Question

instructions on how to make this project please

Answer 1

Simply drop a mentos candy into the neck of a bottle of diet Pepsi. So disguise the Pepsi as a volcano with paper mache and rig up some way to drop the candy in. Then step back, its a mess. Odd class project, this is normally avoided and has little scientific value - are you sure she's not pulling your leg?

Answer 2

I hope this helps you. Here is the experiment I got from my friend who is a Chemistry Teacher. Chemical volcanos are classic projects for science fairs and chemistry demonstrations. The mentos and diet soda volcano is similar to the baking soda volcano, except the eruption is really powerful, capable of producing jets of soda several feet high. It's messy, so you might want to do this project outdoors or in a bathroom. It's also non-toxic, so kids can do this project.
Difficulty: Easy

Time Required: chemical volcano takes a few minutes to set up and erupts for a few seconds

Here's How:
First, gather your supplies. You can substitute another candy for the Mentos, such as M&Ms or Skittles, but ideally you want candies that stack into a neat column with minimal space between them, have a chalky consistency, and barely fit through the mouth of a 2-liter bottle.
Similarly, you could substitute normal soda for diet soda. The project will work just as well, but the resulting eruption will be sticky. Whatever you use, the beverage has to be carbonated!
First, you need to stack the candies. The easiest way to do this is to stack them in a test tube narrow enough to form a single column. Otherwise, you can roll a sheet of paper into a tube just barely wide enough for a stack of candies.
Place an index card over the opening of the test tube or end of the paper tube to hold the candies in the container. Invert the test tube.
Open your full 2-liter bottle of diet soda. The eruption happens very quickly, so set things up: you want the open bottle - index card - roll of candies so that as soon as you remove the index card, the candies will drop smoothly into the bottle.
When you're ready, do it! You can repeat the eruption with the same bottle and another stack of candies. Have fun!


What You Need:
roll of mentos candies
2-liter bottle of diet soda
index card
test tube or sheet of paper
a mop for cleanup

Answer 3

Putting a mento in soda, typically coke, will make "lava" immediatly. Make the volcano shape first, then put the volcano over a bottle or container of soda. When she presents her project, drop in the Mento, and you will have lava.

Hope that helps.
If not Good Luck.

Answer 4

right this is a calming way. that is predicated on the iodine snake, and that's an exceedingly speedy reaction, so confirm you stand decrease back as quickly as you upload the main suitable factor. you prefer: a bottle with a slender neck, potassium iodide, washing up liquid, hydrogen peroxide answer, sodium hydroxide answer, and a few nutrition colouring for a flash of shade to the eruption. place the field you utilize interior a pail or plastic bowl, and place it loose, with newspaper protecting the floor, through fact it gets messy. first of all, use a pH meter to neutralise the hydrogen peroxide answer. this might make it much less good, notwithstanding it is going to additionally act much less as an oxidising agent. This step is finished to steer away from the formation of iodine, which might provide a murky shade to the eruption. next, pour a effective diploma of washing up liquid into the bottle (a 2L lemonade bottle is stable); approximately 50 to seventy 5 mL will do positive. upload from everywhere between 2 and 7 beneficiant scoops of potassium iodide crystals to the bottle. upload a splash of nutrition colouring of your decision, if wanted, to make the eruption have a shade. Now be careful: upload approximately 40-50 mL of the impartial hydrogen peroxide answer AND STEP decrease back! The iodide will catalyse the decomposition of the peroxide, forming oxygen and making the froth shoot out of the bottle (i've got considered it fly up very nearly 10 ft one time).

Answer 6

ive done this before. Put vase for flowers, and a board, just use paper witth glue and water i forget wat that is called, then use the strips of newspaper by connecting from the vase to the base ur using. Then poor salt into the vase, try and use red food dye, and poor the vinegar. Its a classic volcano but it wokrs great,
