The next you travel, especially by airline, pack these convenient, extremely compact and TSA carry-on compliant Dissolving Soap, Body Wash and Shampoo Sheets ($5) in your luggage. These cool little toiletry sheets dissolve instantly in water and are just as effective at cleaning as the real thing. Use one soap sheet for washing your hands or a few of the Body Wash and Shampoo when in the shower. These are also handy to keep in your desk, purse, car or your pocket for whenever you may need to wash up. Best of all, won't it be nice to not have a leaking shampoo bottle in your suitcase for once. (via Michael Kiely)
