hi! I cant tell u how much i appreciate this! thank you so much! sorry but a few more questions. how exactly do u propose i change the temperature of the oobleck? i heated my oobleck on the stove and it hardened almost instantly. as for depth, my oobleck was 6 cm deep in a bucket and i changed it to 4cm and it did not seem to make too much of a difference... the thought of energy did cross my mind although i have no idea why i dint act upon it... so to get things clear, you think energy and not impulse is the factor concerning hardness? so if i just use 1/2 mv2 = Kinetic Energy i should be ok? since right now im using mv for impulse or momentum. i will make momentum/ impulse the same by adjusting the velocities of the light and heavy weight and see what happens. thank you!

Hey! im doing a project on oobleck. i just ran into a bit of trouble. i would highly appreciate some help. I am dropping weights upto 200 grams into the oobleck to find the point at which the impulse(F*dt = mv) is just enough for the weight to rest on the surface for a significant amount of time(say 200 miliseconds). My result is that if 32 gramms weight is dropped from a hieght of 2m then it is just enough impulse(.002) or 1N. I would like to know whether the depth of the oobleck matters for the resistance it provides. also does the temperature matter? Please help me as i need to finish this project asap. Thanks! sorry. the impulse was 0.200352 kgm2s-1
