Real bubbly drink

Dry Ice is dangerous because if it gets on your skin it burns in a cold way. Charlie got some on his hand and he said it hurts a lot. Thats why we had safety glasses  and gloves but it somehow got through Charlie's glove. We put water in a glass, then we put food colouring in  so we had some colour. Then we added some dry ice,  and steam started coming of it straight away. When we added dishwashing liquid it started bubbling - bubbles come flowing over the side in the colour of the food colouring.
THIS IS MY ONE

 I asked Katie if we could put water and dry ice in a container then put a balloon over the top.  The balloon started to blow up. We also blew up a normal balloon and dropped them both from the same height. Can you guess which balloon landed first  - the one we blew up with steam or the one we blew up with our breath?  If you guessed the one with steam then you are correct.

Finger Careful

You might be wondering why I put FINGER CAREFUL as the title?  Well we used 45 minutes rasping a job that an electrical sanders could do in ten minutes. Although we did have to be careful of our fingers because it was connected to the drill. We sanded it so well that it has a shape of the lures. Next week we plan to place the wire in the middle and tinfoil it.
This is me sanding my lure.
