If it had enough free lift to tear free, then once it was free, it would have gone up like a rocket! Instead it drifts, bumps in to the van, and slowly ascends. It would have gone RIP/ZOOOOM to the stratosphere!Unknownhttps://www.blogger.com/profile/14630050225652982967noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-38042104618099820602009-06-05T17:27:02.213-05:002009-06-05T17:27:02.213-05:00Another thing that drove me absolutely crazy: you ...Another thing that drove me absolutely crazy: you cannot steer an unpowered lighter-than-air craft. Those wings will do nothing once the house is moving the same rate as the wind. Hot air balloons can't be steered and neither can a house held up with helium balloons. (Blimps and zeppelins can steer because they are powered, so there's air movement relative to the craft to give rudders something to "bite" into,)<br /><br />Obviously all the scenes with them walking around pulling the floating house were... uh... physically implausible as well.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-34480619.post-4642694557627704772009-06-05T08:10:45.356-05:002009-06-05T08:10:45.356-05:00I figure he waited either because he'd just fi...I figure he waited either because he'd just finished when those guys got there or wanted an "in your face!" moment.

If the tarp was anchored to the ground, then that would make better sense.<br /><br />But then, why did Carl waited till the guys from the retirement home came and about to pick him up? He could have easily floated away as soon as all the balloons were ready!<br /><br />:)<br /><br />Zz.ZapperZhttps://www.blogger.com/profile/15861398273820851809noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-52155873111285278672009-06-05T07:20:38.957-05:002009-06-05T07:20:38.957-05:00When I saw the deployment scene, it looked to me a...When I saw the deployment scene, it looked to me as though the baloons had been held down by a tarp affixed to the ground behind the house. When it came time to deploy, he pulled a ripcord that severed the tarp down the middle, releasing the baloons. If he'd staked the tarp to the ground properly, there'd be no problem holding them there given a sufficient structural integrity of the tarp.Lynxnoreply@blogger.comtag:blogger.com,1999:blog-34480619.post-52166635428542707722009-06-04T17:56:39.909-05:002009-06-04T17:56:39.909-05:00I said the same thing to my wife.

I was willing to suspend my disbelief for the whole idea that some number of balloons could lift the house, but the lift-off really bothered me.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-34480619.post-51610491706593560672009-06-04T13:27:04.061-05:002009-06-04T13:27:04.061-05:00The tarp is still attached to the house, so it sho...The tarp is still attached to the house, so it should still be able to float the house and the tarp. Besides, if the tarp is enough to hold the house and then discarded away from the house when the balloons are deployed, that must be one very heavy tarp!<br /><br />Zz.ZapperZhttps://www.blogger.com/profile/15861398273820851809noreply@blogger.comtag:blogger.com,1999:blog-34480619.post-10208220274271995542009-06-04T10:51:09.572-05:002009-06-04T10:51:09.572-05:00I was also begrudged by the "unleashing"...I was also begrudged by the "unleashing" of the balloons, but there was that tarp-like cover for them. When the balloons were unleashed they floated up to above the house, while before they were (I think) behind it under the cover, meaning that the cover was heavy enough to prevent them from buoying up the house too early. If I'm right, there is still the question of how the hell the old man removed the cover, but it does allay that premature buoyancy problem.<br /><br />My concern is that the kid wasn't on the porch when the house lifted off, because they briefly flashed the porch as the foundation was cracking.Anonymousnoreply@blogger.com
