Kilogram of Feathers

Which is heavier - A kilogram of steel? or a kilogram of Feathers?

In this game, you build towers towards the sky made from steel and feathers!

Be careful not to tip over the scales, though....

drag and drop blocks from the steel and feathers sacks into any side of the scales using your mouse.

Then land them using the WASD keys (like a tetris game).

Each block you land will add weight and tip the scales! 

Steel blocks are heavier than feather blocks, and will affect the scales more.

You need to finish both sacks before you get more blocks!

Get a high score before the scales touch the ground!
