I can't think...my head hurts, It took a little time but I did it

[hazelnut]

click and drag on the item (say the fan fan for example in "blown away" botom left of the screen, it's a tool to use to help move the ball

 

If you do the 'powering up' one, click and drag the battery up to behind the fan and then press test.
