Oz of White Corn Syrup

¶ … oz of white corn syrup and red food dye. Mix to the appearance of blood. I used: A 12-inch square piece of cardboard A 12-inch square piece of lumber A 12-inch square piece of linen Paper towels Tape measure Ruler Observations and Documentation Describe the texture of the surface: The texture of the surface on the carboard was hard; on the linen cloth it was porous; on the lumbar it was hard.

Describe the edge characteristics of the resulting stains The cloth resembled a hot dog / banana shape The blood blot on the paper seemed to me most like that of an embryo Whilst that on the lumbar resembled a kite with a long looping skimpy tail. Describe the extent of peripheral satellite spatter On the cloth there were more splatterings to a right angle of the blob.

On the lumbar it looped off into a thin trail, with outlier splatterings connected by the trail; on the cardboard it was a disfigured shape with precisley one splatter. Measure the diameter of each drop (in millimeters) The measurements: Diameter was approximately 5 by 4 ml on the cardboard. Diameter was approximately 2 by 8ml on the cloth. Diameter was approximately 5 ml. By 2 cm on the lumbar.

Discuss what effect changing the dropping height had on the resulting stains In two cases out of one (on the cloth and on the lumbar) it resulted in a smaller less porous, more flexible blob with a greater production of splatterings. On the cardboard, the result was the reverse: the blob was more rigid than the previous one had been. The 'blood', however, had congealed on tip of pipette and this might have affected results.

Document your observations of the effect of alka selzer on the cleaned up blood; was it what you expected? Why or why not? Did you have difficulty applying the solution? I was expecting a chemical reaction to occur as.
