More fun science

Today we were tasked with two science experiments.  But I didn't have some of the material for one of them so I just did the pepper and dishwashing soap experiment. For this task we had to watch a video and follow the instructions. Our instructions were to get some pepper,dishwashing liquid, a plate and some water. Here's how you do this experiment

First you get a plate and put some water on it, not more than the rim. secondly you sprinkle pepper over all of the water. Touch it once then put your finger in the dishwashing liquid and place your finger in the water again. What happened the first time? And then what happened last? Here is the link to the video and me trying the experiment.

What happens when you put baking soda and vinegar together?

 What happens when you put baking soda and vinegar together?

We have been learning about what happens when you put baking soda and vinegar together. Before we did the experiment we watched a  video  on it and it told us how to do everything. When I did the experiment it took a while to work and fizzed up at the bottom what I wonder if it will do the same it you try it? If you tried the experiment tell me in the comments how it went. Mine went well. Try it out!

You need

Ballon or ziplock bag

Smallest bottle you can find ( doesn't really matter)

Baking soda enough to fill balloon

½ a cup of vinegar

Funnel

Ps . If you're using a ziplock bag only put three teaspoons of baking soda in .

How high will it fly?

 Today we're doing some crazy science we are learning how to use a Aqua pod. I think the Aqua pod will go at least 5 or 6 meters high because I seen people do it before I think  if we do the same thing it will work. So it turned out if did go about the height I guessed let me walk you through the steps we used to make the aqua pod go flying. Do you know what a Aqua pod is? It's basically a orange launch pad for the bottle and something for the pump to connect to.

Firstly you have to fill your bottle (with water) to about 1/3  then you get the aqua pod and tip it upside down so the the water wouldn't spill when you screw the bottle onto the valve. There is a black rubber seal on the valve to stop the water from leaking and dripping.

Secondly you have to connect the  pump to anthor valve and pump it eight times. Then you pull the string and with the pressure for the air that had been pumped into the bottle it make it blast of into the sky. And that's what we did with our Aquapod here's a photo of it.
