  • Once you are done with the painting with cement paint, you will have to wet the surface and cure with water for at least 2 days.
  • Cement paint should be used within 2 hours as it would solidify and become useless after this.

What is the history of treadmills?

At times an invented device may not be useful during it's initial stages but as time passes the utility of the device may become apparent or the device may be used for a very different purpose. One such device is treadmill, an important equipment of the modern day gym was actually used for punishing prisoners during the 1800s. Treadmills were invented in 1818 by an English engineer named Sir William Cubitt. Initial treadmills had a mechanism different from the present day treadmills, requiring the user to step upwards like walking up an endless staircase. 
The prisoners were made to turn a large paddlewheel by stepping on the spokes of the machine. Turning the wheel would in turn pump out water, crush grain, produce electricity, power ventilators in mines etc. Prisoners were often forced to spend up to six hours a day on the wheel in order to utilize their muscle power, to cure their idleness and to do useful work, this was equivalent of climbing about 5,000 to 14,000 feet. So the treadmill was used to torture and punish criminals. They remained in use to punish prisoners until the second half of the 19th century but later they were used to diagnose heart and lung disease in hospitals and  they gradually turned into exercise equipment. Treadmills today are used for various purposes like medical facilities (hospitals, rehabilitation centers, medical and physiotherapy clinics, institutes of higher education), sports clubs, Biomechanics Institute, orthopedic shoe shops, running shops, Olympic training centers, universities, fire-training centers, NASA, test facilities and training rooms of police and army, gyms and even home users.

Do packaged drinking water have an expiry date?

1 user answered

Jeshma Orusu, Hyderabad
User, Level 6 Contributor
Water usually doesn’t have an expiry date but the plastic bottle that contains water has an expiry date so the plastic bottle will eventually expire and will leach chemicals into the drinking water as the bottles are usually made up of polyethylene terephthalate (PET) bottles and high-density polyethylene (HDPE) . The chemicals from the plastic bottle may or may not make the water toxic and harmful but it will definitely change the taste of the water. So, even if the water bottle expires it is still safe to consume the water if and only if the bottle isn’t opened and is properly sealed because the packaging keeps the dust, oxygen, microbes, high heat, pesticides, gasoline and other agents away from the water and thus preventing the water from being spoiled. Also storing the water for too long will change the bottled water’s appearance and smell along with the change in taste but the water will still be safe to consume. According to various food laws all the food products and consumable goods sold should have an expiration date and when Plastic or PET based water bottles are exposed to sunlight for a very long time algae or fungal depositions start taking place which is indicated by a light green tint on the bottle’s surface, water from such plastic containers shouldn’t be consumed. The average time of such micro-bacterial decomposition based on average storage conditions will give the expiry date that is to be displayed on the water bottle, therefore even though water doesn’t have an expiry date it is necessary to display an expiry date on the plastic bottle or contains.
