You cannot prepare helium balloons too far in advance. You should prepare these balloons hours before the event you need them for.

Projectiles. I've had two cracked mini windshields in two years, both caused by gravel flying around in traffic. A mini's windshield is low to the ground and there isn't much of an aerodynamic slipstream to deflect force of impact. If you see debris coming off of other vehicles the best thing to do is slow down and let them get far ahead.
See the Related Links for "US Presidential Elections" to the bottom for the answer. As late as January 26, 1976, Carter was the first choice of only 4% of Democratic voters, according to the Gallup Poll. Yet by mid-March 1976 Carter was not only far ahead of the active contenders for the Democratic presidential nomination, he also led President Ford by a few percentage points. Hope this helps!
According to Google maps, the distance from United Kingdom to United States is 4,242 miles across the North Atlantic Ocean. By air, (as the crow flies) the shortest distance between United States and United Kingdom is 6,848 km= 4,255 miles. These distances are not coast to coast, which would be shorter.
As far as is known he was not.
When ordering balloons, same day delivery offers convenience. Balloons lose helium over time. Ordering too far ahead of your party will leave you flat balloons and extra costs for replacements.
You should see as far ahead as you can. The farther you can see, the more time you have to prepare for whatever your are approaching, and for whatever is approaching you.
Depends on where you buy them and the type of balloons you buy. Obviously, if you want the holographic foiled ones, those are going to cost a bit more. However, there are some affordable balloons you can find online, if you are planning far enough ahead.
You can safely prepare cheese balls 2 - 3 days before serving.
Yes, that is what makes hot air balloons and helium balloons float. Since air is far less dense than water, you need to displace far more air to get an object that floats on water to float in air. That's why hot air balloons are so huge.
Regardless of size, both balloons will burst when atmospheric pressure becomes too much for them. Assuming the helium to rubber/latex ratio is kept the same, both balloons will burst at the same pressure. Depending on where you are in the world and the weather, the atmospheric pressure at one height differs, so it couldn't be said that both balloons will float upwards to the same height, but it can be said that they will fly to the same pressure. Thus the question "Does a little balloon fly as far as a big balloon?" is invalid, but hopefully this answer will suit your wonders.
Hydrogen and helium are, by far, the most abundant substances in the universe.

Helium filled balloons eventually fall because the helium molecules escape from the envelope of the balloon, both at the neck of the balloon and through the material of the balloon itself. The same occurs with air-filled balloons but air-filled balloons do not float to begin with -- they fall to the ground no matter how much air you put in them. In order to float, the gas within the balloon must be lighter (less dense) than the gas outwith the balloon. Inflating a balloon with the same density of gas that surrounds it will not make it float upward because the weight of the balloon alone will make it fall under gravity. Moreover, the elasticity of the balloon compresses the gas within, making it much denser, and therefore heavier.
