Move over, Colin the Caterpillar.
Russell and Belinda Munro created a quite remarkable cake for their 6-year-old son Ewan’s birthday. Check it out:
The couple from Perth, Australia, shared a video of Ewan blowing out his candles before watching the Optimus Prime cake transform.
Russell revealed on Google+ that the cake had a 3D-printed skeleton. He said a motor wound in steel fishing wire attached to the "skeleton" to pull the Transformer into a standing position.
Another motor was used to lift Optimus Prime's head and arms into place.
He said it had taken him a couple of months modifying the mechanics to make sure it worked properly.
