In this DIY design competition, my handmade car model won third prize. I am c1 about DIY. When I am free, I often watch various DIY videos on Bilibili and then try to do some by m2.
Last year, my mum's birthday was coming. So I decided to make some special roses for her. After watching the videos, I bought some materials l3 white plastic roses and some special chemicals online. First, I boiled some water, added the chemicals to it and then put white roses into it to get d4. When the water cooled down, I had beautiful blue roses. I r5 this process many times, creating roses in different colours. When my mum came home and saw the roses, she was so s6 that she couldn't say a word.
Another time, I planned to make some bread. With the help of videos, I q7 let the dough ferment(使面团发酵). Then I put the dough on a plate and placed it in the microwave(微波炉). U8, I made a mistake—I set the baking time too long. In the end, the whole house was f9 with black smoke. Mum and Dad were very angry, but they reminded me to be more careful next time. After all, any h10 must put safety first.
