<p>All right, folks. I hope this post is not gonna get deleted.
I found this: <a href="http://gorillamask.net/mentoscoke.shtml%5B/url%5D">http://gorillamask.net/mentoscoke.shtml</a> Can you tell me how to make this kind of explosive rocket.</p>
<p>Mix menthos and diet coke.</p>
<ol>
<li>All right, but how to make that the bomb explodes exactly when it hits the ground.</li>
<li>Should the bottle be open or closed?</li>
</ol>
<p>Oh, and by the way, is it popular to make such stuff at college?</p>
<p>I am guessing empty out a bit of the coke, and close the menthos in something flimsy (like a semi opened zip lock bag or some semi permeable membrane). The reaction seems to be caused by the menthos reacting with the coke, building up CO2, so all you need to do is to find a way to seperate the two ingredients. The cap should be closed. Its the pressure that causes the thing to fly away, so build up pressure. Theoretically, you can try shaking up a bottle of coke really good and throw it..Should have the same results.</p>
<p>I'm guessing it has a stopper, so upon contact it just pops out.</p>
<p>Edit: yep 90% sure it has a stopper, when there is a voice in the background asking "is it loose enough" hes probably refering to that.</p>
<p>I believe any soda would work.</p>
<p>Actually you don't even need soda. You just need to mix two things that generate some CO2 in a closed vessel.</p>
<p>get your hands on some dry ice. Big explosion.</p>
