Algodoo News continuity error

[RA2lover]

Watch Algodoo in action on the new SMART 800 series board with multitouch/multiuser interface.

as the thread title says, there's a continuity error. try finding it out without using the spoiler!

Spoiler: show

in 0:40~1:00 the users make a balloon. one of the students selects only the balloon itself and applies the helium material to it, but not the chain. when the scene continues, the chain was converted to helium

Dammit man, how the hell do you people find these things? Seriously.

[Mystery]

I noticed when the balloon was going straight up with no struggle. I thought it was some sort of super Algosense.

Good Algosense
The video seems not to show whole action.

The video seems not to show whole action.

Yeah, im sure they cut out parts of the video, such as the girl could have possibly made the chain helium.
