These two water toys are oil based toys. |
| In the first (bubble tube) air is allowed through the oil in uniform sized bubbles
at regular intervals no matter what angle the toy is at. This is my favourite as it stays
the same whatever happens around it. |
| The second (ooze tube) allows a stream of oil to flow into the lower half of the tube at
varying rates depending on the air passing through the oil to the upper half. |
