The first bubble product I just graduated three years ago, I didn't know anything. Today's fragmentary photos remind me of the little things I have paid for the product.

The concept of hand drawing at the beginning.

The preliminary idea, effect diagram, haha, very young, intensity, steering, water storage level, air inlet, etc. were not considered, resulting in proofing 3 times haha

There are still many problems in the first assembly. Using the slow motion of Apple camera, the bubble effect can be seen frame by frame.

For a failed chassis, the water storage level is not enough and the air intake is not enough.

Improved chassis

Test assembly

The improved product, the color helped by friends in Mould City. Although it is not accurate, the effect is still good. I have to do it myself next time.
