Blood Pressure Experiment : Black Pearl Garlic

 Ataya P : The researcher said that eating black garlic is good for your health. It can reduce cholesterol and your blood pressure. So that I tried to testing it with my own body. 

Black Pearl Garlic

Before eating black garlic (123/88 mmHg)

 

 

After ate black garlic for about 20 minute (128/83 mmHg)

As result, My blood pressure SYS value increased from 123 to 128 mmHg (+5 mmHg) and DIA value decreased from 88 to 83 mmHg (-5 mmHg)

I can not said that it working with my body. May be you need to eat the black garlic everyday to be more effective. 

 

PM2.5 Reduce Experiment : Various Masks

Ataya : It's time to testing how good of  various masks can be use to filtering PM2.5 while breathing. I had tissue paper, cloth face mask, surgical mask and PM2.5 mask. Let's see the result ...

All masks and PM2.5 monitor(read before testing at 32 milligram / cubicmeter )

Tissue Paper

Cloth face mask

Surgical Mask

PM2.5 Mask

Tissue Paper : reduced by 32-8 = 24 milligram / cubicmeter 

                            reduce rate = 24/32*100 = 75 %

Cloth Face Mask : reduced by 32-13 = 19 milligram / cubicmeter

                                  reduce rate = 19/32*100 = 59.38 %

Surgical Mask : reduced by 32-10 = 22 milligram / cubicmeter

                              reduce rate = 22/32 *100 = 68.75 %

PM2.5 Mask : reduced by 32-4 = 28 milligram / cubicmeter

                          reduce rate = 28/32*100 =   87.5 %

So, the ranking of masks for filtering PM25 are 1. PM2.5 Mask 2.Tissue Paper 3.Surgical Mask 4.Cloth Face Mask 

In case that you can not afford PM2.5 mask you can use cloth mask with tissue paper inside. Save the world save yourself !!

PM2.5 Reduce Experiment : Electric Fan & Wet Towel

Ataya : It's now PM2.5 season, Air pollution is on the peak rate in Thailand. So I just bought Smartmi PM2.5 monitor and I want to find the way to reduce PM2.5 in my room. The first way is to use electric fan to blow the wind at wet towel. I hope the wet towel can catch some PM2.5 particles. Let's see the result ...

Experimental condition :

• My room was sealed, all windows and door were closed. 
• The room volume is about 4x4x3 cubicmeter.
• On one was in the room during 1 hour of the experiment. 

 

 

PM2.5 before fan On

Just hang wet towel on electric fan and turn it on.

PM2.5 after 1 hour

As result : the PM2.5 was reduced by 43-37 = 6 milligram / cubicmeter 

reduce rate = 6 / 60 =  0.1 milligram/cubicmeter/minute

efficiency rate =( 6 / 43) x 100 = 13.95 %

Hope this information can be helpful for everyone. Save the world save yourself !!
