also, ethanol seems like it would either kill the daphnia or do nothing.

It was hydrated, and it wasnt just h2o2 decomposing. It was longer and violenter than that. The stuff almost came out the tube.

THe purpose of this post is pure curiosity and isnt bad/dangerous in any way. When h2o2 is added to copper sulfate crystals it kinod starts to fizz. When heated a little bit with a lighter it reacts pretty violently. O2 gas is liberated i belive, and when they lighter held over the test tube it burns with a green tinge. what is this reaction? the left over is cuso4 crystals and blue liquid with possibly something else dissolved.

cloning endangered/extinc animals (like the tazmania tiger) is the way to go

if they are gonna use it in pace makers like they said, it would kinda suck if any of that radiation leaked

well i mean, u couldnt turn it all liquid by his method.

no. it would just stop turnig to gas at a point.

ive done the barium hydroxide and ammonium chloride one also. Also adding ammonium nitrate to water gets pretty cold. TO make a really hot one that will boil u can add mg fillings to a solution of cuso4 and also what they use in mre's: finely powdered mg and iron + water.

DNA is a pretty durable molecule. But years of weathering no doubt would destroy it. Have they not found any dinos frozen in the ice somewhere, possibly when it was caught by the iceage? I know they found a mamoth. btw, wat ever happened to it, werent they going to clone it or someting? also, would the dna of a dinosaur stuck in tar be preserved?

Use smoke to make them sleepy. well u probly knew that. Just wondering, but why did you buy bees? seems like an unusual hobby, or is it an addcition to honey you are quenching?

becasue generally smells that smell like that are not good! im sure he meant that kind of as a joke

try using cut tire tubing for the skirt. it may be heavy tho

lasers are considered weopons at our school and the punishment for having one is the same as having a knife.

ya obviously but wat defines that- how filled valence shells are, right?

what are you trying to achieve?

what exactly is the definition of reactivity

anything white will like glow

ive always wanted to try that

also if u have the gases or air or watever pressurized in the iodine ampule already, since there already is pressure built up in there, no iodine should sublime.

hydroxide is a compoun with +OH ion

only if its dry

i was actually thinking : what is up with the weird way gay guys talk. not all of them do, but the ones who do are almost all gay. what makes that happen? delayed geneetics or sometin... ?

my friend made one with computer fans (12 v ones and 3 of em) on a plexiglass sheet about 1.5 ft across and like 1/4 in thick. He used a tire tube on the bottom as the skirt. it was really simple and didnt work like at all. With hover crafts it is very, very important to have them be as light as possible and just have one super strong fan blowing down the skirt. And the plexiglass he used was way to heavy. U can buy alot of the parts needed online like proper motors and skirts and such.

it cant be that scary. its only gas. And its not like its mixed with alot of oxygen either. On the other hand i have never done anything with acetylene.

may i ask why u wanted to know ?
