The products that Kickstarter, Indigogo or other crowdfunding sites have are not necessarily technology-intensive. Many are products that are easily seen in daily activities. BoilingBeeper is one of such products.
This product is a kitchen gadget. It alerts users when the water is boiling. Users can safely remove it from the pot because its top floats in the pot. The product says its material is US FDA-approved safe.
“There is no switch on the product, but water sensor on the bottom. The sensor is automatically activated when a user puts it in the water, switching on or off. It beeps when the water begin to boil, which makes it useful for a pot that does not sound when the water is boiling.”
This product secured funds from a crowdfunding site, Kickstarter. More information on the product can be found here.
