1. We don’t really like this idea, because belt will load the backs of our grandparents. There is no needed to warm up backs because the weather is hot in summer. Also, you can’t put the basic tools (shovels, rakes) 

2. This idea already exists – a watering can. 

3. We are really like this tomatoes idea. It’s a good idea, but the only drawback that needs to be finalized is that not all tomatoes ripen the same way 

4. It is not customary to hold festivals in our country, also it  would be difficult for grandmothers to bear their fruits. For young generation this kind of event isn’t so interesting
