Soap the soap box. Putting the bottle cap in the soap box can keep the soap out of contact with the water at the bottom of the box and save the soap. Make washboards. Collect some bottle caps on discarded medicine bottles (such as rubber caps on penicillin bottles). ), and then nail them in rows on a rectangular board according to the crisscross position (the nails must be nailed in the depression of the bottle cap), which becomes a very practical washboard.

Stop itching. It is unbearable to be bitten by mosquitoes in summer. You can put the lid of the thermos bottle on the mosquito bite and rub it for 2 -3 seconds, then take it off for 2 -3 times in a row. Severe itching will disappear immediately, and local erythema will not appear. The bottle cap is preferably a thermos bottle with a water temperature of about 90℃. Grow flowers.
