Science Buddies: "Ask an Expert"

Hello! I am measuring blood spatter. What could I use as something to be hit/the target? I need something that will hold the fake blood and act almost like flesh over soft tissue.



Thank you

Hi jacobd740,

This is sure to be a fun and interesting project! I would suggest using something like a household sponge. Although the sponge doesn't have 'skin' (like we do), it will mimic a blunt-force blood-shedding event quite well (at least simulating an already bleeding injury). You can also vary your experiment by observing the effect of different volumes of your blood simulant absorbed into the sponge.

If you are interested in trying to create a skin simulant, try and think of something (inexpensive!) that may act like skin and give it a try!

Also, as I am not entirely sure which science fair project you are attempting, I would like to add a quick word of caution: depending on your choice of blood simulant and the method of generating the bloodspatter, please use all suitable and necessary precautions - and check with your project supervisor or teacher before starting.

Good luck!
Geoff.

Thank you for the incite

What if i wrapped the sponge in tissue paper?
I would act as more of a surface tensioner.
It would also be moist from absorbing the Blood.

oh and by the way i am using a fake blood recipe involving corn syrup.
I did this to avoid any viruses or other problems.

Thank you

Hi jacobd740,

Tissue paper would certainly be a great start! Just make sure that the sponge you are using as your target is not saturated with your blood substitute. (This goes back to my suggestion of trying different volumes of your fake blood.)

And thank you for the info regarding what you are planning on using as your "blood"! Please still take care to wear safety goggles and suitable protective clothing when carrying out your experiment - it gets messy

Please keep us informed of your progress and good luck!
Geoff.

Thank you for the input and i agree not to saturate the spuonge.
I will make sure to take verry much percaution thank y
I will keep you informed as i go along.

Thank You All

Hi jacobd740,

I did the default by inputing "what is the viscosity of blood at 37 degrees celsius" to answers.com.

The second web result: http://www.madsci.org/posts/archives/19 ... .Me.r.html directly answers your question!

Rarely does the web offer such instant gratification!
